The number of reports concerning Escherichia coli clinical isolates that produce glutathione S-transferases responsible for fosfomycin resistance (FR-GSTs) has been increasing. We have developed a disk-based potentiation test in which FR-GST producers expand the growth inhibition zone around a Kirby-Bauer disk containing fosfomycin in combination with sodium phosphonoformate (PPF). PPF, an anal...
Curcuma purpurascens Bl., belonging to the Zingiberaceae family, is known as temu tis in Yogyakarta, Indonesia. In this study, the hydrodistilled dried ground rhizome oil was investigated for its chemical content and antiproliferative activity against selected human carcinoma cell lines (MCF7, Ca Ski, A549, HT29, and HCT116) and a normal human lung fibroblast cell line (MRC5). Results from GC-M...
Aclacinomycin methylesterase (RdmC) is one of the tailoring enzymes that modify the aklavinone skeleton in the biosynthesis of anthracyclines in Streptomyces species. The crystal structures of this enzyme from Streptomyces purpurascens in complex with the product analogues 10-decarboxymethylaclacinomycin T and 10-decarboxymethylaclacinomycin A were determined to nominal resolutions of 1.45 and ...
Most marine invertebrates have dispersive larvae and relatively immobile adults. These developmental stages are linked by a settlement event, which is often mediated by specific cues in bacterial biofilms. While larvae distinguish between biofilms from different environments, it remains unknown if they receive information from all, only a few or even just a single bacterial species in natural b...
Abstract With occurrence mainly in the southwest Goiás, Butia purpurascens has fruits and leaves widely extracted by regional population. Coexists with exotic grasses, frequent burnings cattle’s grazing trampling. Young individuals are rarely seen. We aim to provide information about propagules, seedling formation monitoring of saplings B. until adults reproductive phase. Fruits were selected, ...
We detected potent angiostatic activity in a MeOH extract from the mycelia of microbial strain S-45628 in the chick chorioallantoic membrane (CAM) assay. The producer was taxonomically characterized as Streptomyces purpurascens. Active principles designated TAN-1323 A-D were isolated and determined to be 18-membered macrolide antibiotics; components C and D are new members of this group, while ...
