| streptomyces drozdowiczii sp. nov., a novel cellulolytic streptomycete from soil in brazil. | an actinomycete strain, isolated from a mata atlântica soil sample, showing cellulolytic activity was subjected to polyphasic taxonomic characterization to determine its identity. strain m7at presented morphological and chemotaxonomic characteristics consistent with its assignment to the genus streptomyces. phylogenetic analysis of its 16s rdna sequence revealed that the strain differed from described streptomycetes available in the public databases; the most closely related species was streptom ... | 2004 | 15280309 |
| streptomyces brevispora sp. nov. and streptomyces laculatuspora sp. nov., novel actinomycetes isolated from soil. | the taxonomic positions of two actinomycetes isolated from a hay meadow soil sample were determined using a polyphasic approach. the isolates had chemical and morphological properties typical of streptomycetes and formed a distinct 16s rrna gene subclade together with the type strain of streptomyces drozdowiczii nrrl b-24297t. dna:dna relatedness studies showed that the three strains belonged to different genomic species. the organisms were also distinguished using a combination of phenotypic pr ... | 2011 | 21478394 |
| lignocellulose-adapted endo-cellulase producing streptomyces strains for bioconversion of cellulose-based materials. | twenty-four actinobacteria strains, isolated from arundo donax, eucalyptus camaldulensis and populus nigra biomass during natural biodegradation and with potential enzymatic activities specific for the degradation of lignocellulosic materials, were identified by a polyphasic approach. all strains belonged to the genus streptomyces (s.) and in particular, the most highly represented species was streptomyces argenteolus representing 50% of strains, while 8 strains were identified as streptomyces f ... | 2016 | 28066379 |
| deciphering the biosynthetic origin of l-allo-isoleucine. | the nonproteinogenic amino acid l-allo-isoleucine (l-allo-ile) is featured in an assortment of life forms comprised of, but not limited to, bacteria, fungi, plants and mammalian systems including homo sapiens. despite its ubiquity and functional importance, the specific origins of this unique amino acid have eluded characterization. in this study, we describe the discovery and characterization of two enzyme pairs consisting of a pyridoxal 5'-phosphate (plp)-linked aminotransferase and an unprece ... | 2016 | 26669414 |
| biosynthesis of the anti-infective marformycins featuring pre-nrps assembly line n-formylation and o-methylation and post-assembly line c-hydroxylation chemistries. | the biosynthetic gene cluster governing production of anti-infective marformycins was identified from deep sea-derived streptomyces drozdowiczii scsio 10141. the putative mfn gene cluster (45 kb, 20 orfs) was found to encode six nrpss and related proteins for cyclodepsipeptide core construction (mfncdefkl), a methionyl-trna formyltransferase (mfna), a sam-dependent methyltransferase (mfng), and a cytochrome p450 monooxygenase for piperazic acid moiety hydroxylation (mfnn); notably, only mfnn use ... | 2015 | 25746634 |
