inversion of lipase stereospecificity for fluorogenic alkyldiacyl glycerols. effect of substrate solubilization.we synthesized enantiomeric 1-o-alkyl-2,3-diacyl-sn-glycerol and 3-o-alkyl-1,2-diacyl-sn-glycerol containing pyrene as a fluorescent reporter and the trinitrophenylamino residue as a fluorescence quencher; both reporter groups were covalently bound to the omega end of the acyl chains at positions sn-2 and sn-3(1), respectively. the fluorescence of the intact substrate molecules was very low. chemical or enzymic release of the fatty acyl chains lead to fluorescence dequenching. the rate of lipoly ...19957628484
construction and heterologous expression of a synthetic copy of the cutinase cdna from fusarium solani pisi.a copy of the cutinase cdna from fusarium solani pisi was constructed starting from synthetic oligonucleotides. for this construction three separate cassettes were made, which were subsequently assembled to form the cutinase gene. heterologous expression of the synthetic cutinase gene and the subsequent secretion of the recombinant enzyme was achieved in saccharomyces cerevisiae and aspergillus awamori.19957632392
hyalohyphomycoses due to fusarium spp.--two case reports and review of the literature.we report a case of a severe fusarium solani keratitis in a 82-year-old patient with a history of surgical trauma. antimycotic therapy and keratoplasty led to markedly improved vision. identification of the fungus was complicated by the fact that the isolate did not produce the typical macroconidia. the second case was a fatal disseminated fusarium verticillioides infection in a 69-year-old patient during neutropenia after chemotherapy of acute myelogenous leukemia. the patient developed pneumon ...19957637684
the fusarium solani gene encoding kievitone hydratase, a secreted enzyme that catalyzes detoxification of a bean phytoalexin.among the antimicrobial phytoalexins produced by phaseolus vulgaris (french bean) is the prenylated isoflavonoid, kievitone. the bean pathogen, fusarium solani f. sp. phaseoli, secretes a glycoenzyme, kievitone hydratase (ec 4.2.1.95), which catalyzes conversion of kievitone to a less toxic metabolite. among f. solani strains, those that are highly virulent to p. vulgaris also produce kievitone hydratase constitutively, suggesting that the enzyme is a virulence factor. based on the n-terminal am ...19957655061
induction of a tomato anionic peroxidase gene (tap1) by wounding in transgenic tobacco and activation of tap1/gus and tap2/gus chimeric gene fusions in transgenic tobacco by wounding and pathogen attack.the anionic peroxidase genes of tomato, tap1 and tap2, are induced by wounding in tomato fruits and by elicitor treatment in cell suspension cultures. these homologous genes code for anionic peroxidases that are postulated to cause polymerization of the phenolic residues into wall polymers in wound-healing and pathogen-infected tissues. an expression construct containing the entire tap1 gene with its 5' and 3' flanking sequences was introduced into tobacco by agrobacterium tumefaciens-mediated g ...19937678769
construction of a recombinant wine yeast strain expressing a fungal pectate lyase gene.a gene fusion between the saccharomyces cerevisiae actin gene promoter and the cdna of the fusarium solani f. sp. pisi pela gene has been constructed. this expression cassette has been introduced into the industrial wine yeast strain t73. the resulting recombinant strain is able to secrete active pela enzyme into the culture medium. in preliminary microvinification experiments the wine produced by this pectinolytic strain is indistinguishable from wine produced using the non-transformed strain o ...19957729670

cloning and expression of cdna encoding a protein that binds a palindromic promoter element essential for induction of fungal cutinase by plant cutin.previous studies showed that a palindromic sequence located at -159 base pairs is essential for induction of cutinase gene in fusarium solani f. sp. pisi (nectria haematococca mating type vi) by the hydroxy fatty acids from plant cutin and that a 50-kda nuclear protein binds to a promoter that contains this element. screening of a phage lambda gt11 expression library with the concatenated palindromic sequence as the probe identified a cdna encoding a palindrome-binding protein (pbp). nucleotide ...19957744822
in vitro transcription from the nectria haematococca pda1 promoter in an homologous extract reflects in vivo pisatin-responsive regulation.the pda1 gene of nectria haematococca mp vi (anamorph: fusarium solani) encodes pisatin demethylase. this enzyme detoxifies the isoflavanoid phytoalexin pisatin produced by the plant on which this fungus is pathogenic. expression of pisatin demethylase activity is induced in a mycelium by pretreatment with pisatin. we have developed homologous in vitro system which accurately initiates transcription from the pda1 promoter. transcription levels in vitro reflect the same pisatin-responsive stimula ...19947750146
surface signaling in pathogenesis.surface signaling plays a major role in fungal infection. topographical features of the plant surface and chemicals on the surface can trigger germination of fungal spores and differentiation of the germ tubes into appressoria. ethylene, the fruit-ripening hormone, triggers germination of conidia, branching of hyphae, and multiple appressoria formation in colletotrichum, thus allowing fungi to time their infection to coincide with ripening of the host. genes uniquely expressed during appressoria ...19957753774
cutinase from fusarium solani pisi hydrolyzing triglyceride analogues. effect of acyl chain length and position in the substrate molecule on activity and enantioselectivity.triglyceride analogues were synthesized in which one of the primary acyl ester functions has been replaced by an alkyl group and the secondary acyl ester bond has been replaced by an acyl amino bond. the chain length at either position was varied, and both (r)- and (s)-enantiomers of each compound were synthesized. these pseudo triglycerides contain only one hydrolyzable ester bond, and they are ideally suited to studying the influence of the chain length at the 1-, 2-, and 3-position on lipase ...19957756270

molecular cloning and characterization of a pea chitinase gene expressed in response to wounding, fungal infection and the elicitor chitosan.the fungicidal class i endochitinases (e.c.3.3.1.14, chitinase) are associated with the biochemical defense of plants against potential pathogens. we isolated and sequenced a genomic clone, dah53, corresponding to a class i basic endochitinase gene in pea, chi1. the predicted amino acid sequence of this chitinase contains a hydrophobic c-terminal domain similar to the vacuole targeting sequences of class i chitinases isolated from other plants. the pea genome contains one gene corresponding to t ...19957787175
[severe keratomycosis. diagnosis and treatment].we reported three consecutive cases of severe fungal keratitis initially undiagnosed by corneal scrapping. corneal biopsy showed fungal elements of paecilomyces lilacinus, fusarium solani, scedosporium apiospermum. most cases of fungal keratitis could be treated successfully if adequate antifungal therapy were started early. early and accurate diagnosis is of major importance. the results of our cases confirm the superiority of corneal biopsy over corneal scrapping. corneal biopsy is a procedure ...19947822693
disseminated fusarium solani infection.disseminated fungal infections commonly occur in immunocompromised hosts; candida spp. are the most common. fusarium spp., soil saprophytes once considered pathogenic only in plants, have emerged as serious pathogens in neutropenic patients with malignancies. we describe two patients, one with acute myelogenous leukemia and the other with metastatic breast cancer, in whom disseminated fusarium solani infection developed. both patients had neutropenia and fever when generalized, tender, erythemat ...19957829738
in vitro transcription and binding analysis of promoter regulation by a host-specific signal in a phytopathogenic fungus.the pda1 promoter of the phytopathogennectria haematococca mpvi (anamorph fusarium solani) offers a model for regulation of a fungal virulence gene in response to plant host-specific signals. expression of the pda1 gene, encoding pisatin demethylase, is induced in culture by pisatin, the isoflavanoid phytoalexin of pea. this pisatin induction is suppressed by nutritional factors. we have been studying the mechanism of pisatin induction through in vitro identification of regulatory factors and re ...19947847884
glyceride synthesis catalyzed by cutinase using the monomolecular film technique.the monomolecular film technique previously used to study the kinetics of lipase hydrolysis was adapted to synthesizing oleoyl glycerides (monoolein, diolein, and triolein). the water subphase was replaced by glycerol, and a film of oleic acid was initially spread on the glycerol surface. in this system a recombinant cutinase from fusarium solani was able to catalyze oleoyl glyceride synthesis. more than 50% of the oleic acid film was acylated after 7 min of reaction. the surface pressure applie ...19957849021
