Abstract excerpt
Phenylalanine 4-monooxygenase is the key enzyme in the sulfoxidation of the thioether drug S-carboxymethyl-l-cysteine and its thioether metabolites, S-methyl-l-cysteine, N-acetyl-S-carboxymethyl-l-cysteine and N-acetyl-S-methyl-l-cysteine in humans, and a number of other mammalian species. The kinetics constants of the sulfoxidation reaction (K(m), V(max) and CL(E)) have been investigated in cytosolic fractions...
