Trehalose metabolism in germinating spores of Streptomyces hygroscopicus.
Evidence is presented which indicates that utilization of trehalose is an early event in spore germination in Streptomyces hygroscopicus. Early in spore germination and before any increase in cell mass, the activity of trehalase increased more than 15-fold, while the intracellular content of trehalose fell to very low levels. On the other hand, increased activity of the trehalose phosphate synt...
متن کاملDraft Genome Sequence of Streptomyces hygroscopicus subsp. hygroscopicus NBRC 16556
Here, we report the draft genome sequence of strain NBRC 16556, deposited as Streptomyces hygroscopicus subsp. hygroscopicus into the NBRC culture collection. An average nucleotide identity analysis confirmed that the taxonomic identification is correct. The genome sequence will serve as a valuable reference for genome mining to search new secondary metabolites.
متن کاملNew geldanamycin analogs from Streptomyces hygroscopicus.
Geldanamycin (GM) and its analogs are important anticancer agents that inhibit heat shock protein (Hsp) 90, which is a major chaperone protein in cancer cells. Accordingly, based on interest in obtaining novel natural GM derivatives, the potential of Streptomyces hygroscopicus JCM4427, a GM producer, was explored for novel natural GM derivative(s), resulting in the discovery of new GM analogs a...
متن کاملStreptomyces hygroscopicus has two glutamine synthetase genes.
Streptomyces hygroscopicus, which produces the glutamine synthetase inhibitor phosphinothricin, possesses at least two genes (glnA and glnB) encoding distinct glutamine synthetase isoforms (GSI and GSII). The glnB gene was cloned from S. hygroscopicus DNA by complementation in an Escherichia coli glutamine auxotrophic mutant (glnA). glnB was subcloned in Streptomyces plasmids by insertion into ...
متن کاملA new geldanamycin analogue from Streptomyces hygroscopicus.
A new geldanamycin analogue was isolated from Streptomyces hygroscopicus A070101. The structure was elucidated as 11-methoxy-17-formyl-17-demethoxy-18-O-21-O-dihydrogeldanamycin (1) on the basis of extensive 1D and 2D NMR as well as HRESI-MS spectroscopic data analysis. Compound 1 showed considerable cytotoxicity (SRB) against human cancer cell lines (breast cancer MCF-7, skin melanoma SK-MEL-2...
