Hopanoids are not essential for growth of Streptomyces scabies 87-22.
Hopanoids are triterpenoic, pentacyclic compounds that are structurally similar to sterols, which are required for normal cell function in eukaryotes. Hopanoids are thought to be an important component of bacterial cell membranes because they control membrane fluidity and diminish passive diffusion of ions, and a few taxons modulate their hopanoid content in response to environmental stimuli. H...
متن کاملThe plant pathogen Streptomyces scabies 87-22 has a functional pyochelin biosynthetic pathway that is regulated by TetR- and AfsR-family proteins.
Siderophores are high-affinity iron-chelating compounds produced by bacteria for iron uptake that can act as important virulence determinants for both plant and animal pathogens. Genome sequencing of the plant pathogen Streptomyces scabies 87-22 revealed the presence of a putative pyochelin biosynthetic gene cluster (PBGC). Liquid chromatography (LC)-MS analyses of culture supernatants of S. sc...
متن کاملAntibacterial substance produced by Streptomyces sp . No . 87
An antimicrobial substance produced by Streptomyces sp. No. 87 was partially purified and studied for its antibacterial characteristics using the swab paper disc technique. The cell-free culture filtrate showed antibacterial activity against several species of pathogens including Gram-positive bacteria, i.e. Bacillus cereus ATCC 11778, B. subtilis TISTR 008, B. megaterium, Staphylococcus aureus...
متن کاملCloning and expression of a gene from Streptomyces scabies encoding a putative pathogenicity factor.
We cloned a 9.4-kb DNA fragment from Streptomyces scabies ATCC 41973 that allows the nonpathogen Streptomyces lividans 66 TK24 to necrotize and colonize potato tuber slices and produce scab-like symptoms on potato minitubers. Deletion analysis demonstrated that activity was conferred by a 1.6-kb DNA region. Sequence analysis of a 2.4-kb DNA fragment spanning the DNA region necessary for activit...
