Desulfovibrio vulgaris, biofilm formation and T3SS Inhibition
Desulfovibrio vulgaris Hildenborough is a Gram-negative sulfate-reducing bacterium (SRB). It has ability to adhere to the surfaces forming biofilm. It can seriously impact environmental sites including metal pipelines, oil repositories and radionuclide waste sites. Due to increased antibiotic resistance among bacterial pathogens, treatment for infectious diseases is getting ineffective. There s...
متن کاملCharacterization of a trithionate reductase system from Desulfovibrio vulgaris.
A trithionate reductase system was isolated and purified from extracts of Desulfovibrio vulgaris. This system reduced trithionate to thiosulfate and consisted of two proteins. One was bisulfite reductase, an enzyme that reduces bisulfite to trithionate, and the second component was designated TR-1. Both enzymes were required to reduce trithionate to thiosulfate. Flavodoxin and cytochrome c3 fro...
متن کاملRole of thiosulfate in bisulfite reduction as catalyzed by Desulfovibrio vulgaris.
Studies with (35)S-labeled substrates were conducted to investigate the pathway involved in the reduction of sulfite to sulfide by cell-free extracts of the sulfate-reducing organism Desulfovibrio vulgaris. The results showed that accumulation of thiosulfate occurred when crude extracts were incubated under appropriate conditions with sulfite as substrate. With labeled sulfite as substrate, thi...
متن کاملOn the mechanism of adenylyl sulfate reductase for the sulfate-reducing bacterium, Desulfovibrio vulgaris.
NADH dehydrogenases have been isolated in a low-molecular weight form (56,500) from both low-iron and normal-iron grown cells of Azotobacter vinelandii. Unlike low-molecular weight forms of NADH dehydrogenases reported from mammalian mitchondria, the enzymes in this study have not undergone any unusual alterations in various reactivities with substrates and electron acceptors. The NADH dehydrog...
متن کاملBiochemical Function, Molecular Structure and Evolution of an Atypical Thioredoxin Reductase from Desulfovibrio vulgaris
Thioredoxin reductase (TR) regulates the intracellular redox environment by reducing thioredoxin (Trx). In anaerobes, recent findings indicate that the Trx redox network is implicated in the global redox regulation of metabolism but also actively participates in protecting cells against O2. In the anaerobe Desulfovibrio vulgaris Hildenborough (DvH), there is an intriguing redundancy of the Trx ...
