| lentzea gen. nov., a new genus of the order actinomycetales. | we describe a new genus of mesophilic actinomycetes, for which we propose the name lentzea. the strains of this genus form abundant aerial hyphae that fragment into rod-shaped elements. whole-cell hydrolysates contain the meso isomer of diaminopimelic acid and no characteristic sugar (wall chemotype iii). the phospholipid pattern type is type pii (phosphatidylethanolamine is the characteristic phospholipid); the major menaquinone is mk-9. the fatty acid profile comprises saturated, unsaturated, ... | 1995 | 7537071 |
| numerical and chemical classification of streptosporangium and some related actinomycetes. | one hundred and seventeen streptosporangia from soil were compared with marker strains of the family streptosporangiaceae for many phenotypic properties. the data were examined using the jaccard, pattern and simple matching coefficients with clustering achieved using average, complete and single linkage algorithms. particular confidence was placed in the product of the pattern, average linkage analysis given the sharp definition of aggregate groups and clusters and a combination of low test erro ... | 1993 | 8085797 |
| phylogenetic analysis of saccharothrix and related taxa: proposal for actinosynnemataceae fam. nov. | partial sequences for 16s rdna were determined for strains of the genus saccharothrix, including most described species, as well as strains of the described species of the related genera kutzneria, actinokineospora and actinosynnema. these were aligned with published sequences for other species of these genera, as well as those of the genera 'actinoalloteichus', 'asiosporangium', lentzea, kutzneria, streptoalloteichus and representative taxa from other actinomycete families. phylogenetic analysi ... | 2000 | 10826820 |
| kutznerides 1-4, depsipeptides from the actinomycete kutzneria sp. 744 inhabiting mycorrhizal roots of picea abies seedlings. | bioassay-guided fractionation of culture supernatants of the actinomycete kutzneria sp. 744 resulted in the isolation of four new depsipeptides (1-4). structure analysis revealed the general structure: cyclo[2-(1-methylcyclopropyl)-d-glycine-(2s,3ar,8as)-6,7-dichloro-3a-hydroxy-1,2,3,3a,8,8a-hexahydropyrrolo[2,3-b]indole-2-carboxylic acid-3-hydroxy-d-glutamic acid-o-methyl-l-serine-l-piperazic acid-(s)-2-hydroxy-3,3-dimethylbutanoic acid]. the 3-hydroxy-d-glutamic acid was present as its threo-i ... | 2006 | 16441076 |
| low-abundance kutznerides from kutzneria sp. 744. | five new (5-9) and four known (1-4) kutznerides were isolated from the actinomycete kutzneria sp. 744. compounds 1-9 all consisted of a cyclohexadepsipeptide core with the general structure 2-(1-methylcyclopropyl)-d-glycine-(2s,3ar,8as)-6,7-dichloro-3a-hydroxy-1,2,3,3a,8,8a-hexahydropyrrolo[2,3-b]indole-2-carboxylic acid-3-hydroxy-d-glutamic acid-o-methyl-l-serine-l-piperazic acid-(s)-2-hydroxy-3,3-dimethylbutyric acid. compounds 5, 6, and 8 contained erythro-3-hydroxy-d-glutamic acid, whereas 7 ... | 2006 | 17190458 |
| proposal for the new genus allokutzneria gen. nov. within the suborder pseudonocardineae and transfer of kibdelosporangium albatum tomita et al. 1993 as allokutzneria albata comb. nov. | during the course of phylogenetic analyses based on 16s rrna gene sequences for all currently described taxa within the family pseudonocardineae, it became evident that kibdelosporangium albatum dsm 44149(t) was misplaced within the genus kibdelosporangium and is phylogenetically most closely related to the genus kutzneria. chemotaxonomic analyses revealed that kibdelosporangium albatum differed from kutzneria in containing arabinose as well as galactose and mannose as diagnostic whole-cell suga ... | 2008 | 18523197 |
| biosynthetic chlorination of the piperazate residue in kutzneride biosynthesis by kthp. | kutznerides 2 and 8 of the cyclic hexadepsipeptide family of antifungal natural products from the soil actinomycete kutzneria sp. 744 contain two sets of chlorinated residues, a 6,7-dichloro-hexahydropyrroloindole moiety derived from dichloro-tryptophan and a 5-chloro-piperazate moiety, as well as a methylcyclopropylglycine residue that may arise from isoleucine via a cryptic chlorination pathway. previous studies identified ktzd, ktzq, and ktzr as three halogenases in the kutzneride pathway, bu ... | 2011 | 21648411 |
