Defects in both of the genes coding for the cytosolic superoxide dismutases (SODs) of Escherichia coli impose an oxygen-dependent nutritional requirement for cysteine. This is now seen to be a bradytrophy, rather than an absolute auxotrophy, since la

In both Salmonella typhimurium and Escherichia coli, CysB is a LysR family transcriptional activator, which regulates genes of the cysteine regulon. Transcription activation of cys genes also requires an inducer, N-acetyl-L-serine, and cysB mutants t

S -Adenosylmethionine (AdoMet), inorganic pyrophosphate (PP i ) and inorganic phosphate (P i ) are potent product inhibitors of AdoMet synthetase and have been postulated to play a role in increasing AdoMet levels and turnover in peripheral blood mon

The flavoprotein and hemoprotein components of Escherichia coli B NADPH-sulfite reductase are encoded by cysJ and cysI, respectively. Plasmids containing these two genes overexpressed flavoprotein catalytic activity and apohemoprotein by 13- to 35-fo

A steady-state kinetic analysis of human S-adenosylmethionine synthetase indicates that the reaction is Bi Ter with ordered addition of ATP and L-methionine and release of S-adenosylmethionine as the first product. Pyrophosphate and phosphate are the

The cysteine regulon of Salmonella typhimurium is positively regulated by the CysB protein and an inducer, which can be either O-acetyl-L-serine or N-acetyl-L-serine. In vivo experiments confirmed that sulfide and L-cysteine (supplied as L-cystine) i

O-Acetylserine sulfhydrylase-A (OASS-A) is a pyridoxal 5'-phosphate (PLP) dependent enzyme from Salmonella typhimurium that catalyzes the beta-replacement of acetate in O-acetyl-L-serine (OAS) by sulfide to give L-cysteine. The reaction occurs via a

Expression of the cysteine regulon in Salmonella typhimurium and Escherichia coli is controlled by the LysR-type transcriptional activator CysB and by the inducer N-acetyl-L-serine. Sulphide and thiosulphate are anti-inducers. Two highly purified con
