Cysteine conjugate S-oxidase activity, with S-benzyl-L-cysteine as substrate, was found mostly in the microsomal fractions of rat liver and kidney. In the presence of oxygen and NADPH, S-benzyl-L-cysteine is converted to S-benzyl-L-cysteine sulfoxide; no S-benzyl-L-cysteine sulfone was detected. The Vmax

To explore the possibility of utilizing cysteine derivatives for technetium-99m radiopharmaceutical preparation with clinical potential, we synthesized two benzyl substituted cysteine compounds, namely, S-benzyl cysteine 1 and cysteine benzyl ester 3. It was expected, from our previous studies on benzoyl

We investigated the capacity and the localization of N-acetylation of the mercapturic acid precursor S-benzyl-L-cysteine (BC), as well as the tubular reabsorption of this compound in the rat kidney in vivo et situ by renal clearance and continuous microinfusion and

Lysine 269 in Escherichia coli tryptophan indole-lyase (tryptophanase) has been changed to arginine by site-directed mutagenesis. The resultant K269R mutant enzyme exhibits kcat values about 10% those of the wild-type enzyme with S-(o-nitrophenyl)-L-cysteine, L-tryptophan, and S-benzyl-L-cysteine, while kcat/Km values are

Previously, it was shown that beta-elimination of selenocysteine Se-conjugates by rat renal cytosol leading to pyruvate formation was not solely catalyzed by pyridoxal phosphate-dependent enzymes. It was hypothesized that selenoxidation of the selenocysteine Se-conjugates, followed by syn-elimination, may be an
