Purification and characterization of phosphonoglycans from Glycomyces sp. strain NRRL B-16210 and Stackebrandtia nassauensis NRRL B-16338.
Two related actinomycetes, Glycomyces sp. strain NRRL B-16210 and Stackebrandtia nassauensis NRRL B-16338, were identified as potential phosphonic acid producers by screening for the gene encoding phosphoenolpyruvate (PEP) mutase, which is required for the biosynthesis of most phosphonates. Using a variety of analytical techniques, both strains were subsequently shown to produce phosphonate-con...
متن کاملComplete genome sequence of Stackebrandtia nassauensis type strain (LLR-40K-21T)
Stackebrandtia nassauensis Labeda and Kroppenstedt (2005) is the type species of the genus Stackebrandtia, and a member of the actinobacterial family Glycomycetaceae. Stackebrandtia currently contains two species, which are differentiated from Glycomyces spp. by cellular fatty acid and menaquinone composition. Strain LLR-40K-21(T) is Gram-positive, aerobic, and nonmotile, with a branched substr...
متن کاملEarthworm Is a Versatile and Sustainable Biocatalyst for Organic Synthesis
A crude extract of earthworms was used as an eco-friendly, environmentally benign, and easily accessible biocatalyst for various organic synthesis including the asymmetric direct aldol and Mannich reactions, Henry and Biginelli reactions, direct three-component aza-Diels-Alder reactions for the synthesis of isoquinuclidines, and domino reactions for the synthesis of coumarins. Most of these rea...
متن کاملTowards a biocatalyst for (S)-styrene oxide production: characterization of the styrene degradation pathway of Pseudomonas sp. strain VLB120.
In order to design a biocatalyst for the production of optically pure styrene oxide, an important building block in organic synthesis, the metabolic pathway and molecular biology of styrene degradation in Pseudomonas sp. strain VLB120 was investigated. A 5.7-kb XhoI fragment, which contained on the same strand of DNA six genes involved in styrene degradation, was isolated from a gene library of...
متن کاملBiochemical and Immunochemical Characterization of Hexosaminidase Pt
Hexosaminidase P, the main isozyme of hexosaminidase in pregnancy serum, was isolated and purified 600-700-fold by a two-step purification procedure-affinity chromatography on Sepharose-bound eaminocaproyl-Nacetylglucosylamine, followed by ion-exchange chromatography on DEAE-cellulose. The purified enzyme was subjected to biochemical and immunochemical analysis. Its catalytic property, namely, ...
