WebDec 9, 2024 · Many enzymes require pyridoxal 5’-phosphate (PLP) as an essential cofactor and share active site residues in mediating diverse enzymatic reactions. Methionine can be converted into cysteine by cystathionine γ-lyases (CGLs) through a transsulfuration reaction dependent on PLP. In bacteria, MccB, also known as YhrB, exhibits CGL activity … WebJun 23, 1998 · Despite a high catalytic constant (30 s −1 ), the high Km values for OPH and cysteine (2.5 and 0.46 mM, respectively) exhibited by the Arabidopsis enzyme raise the question of cystathionine γ-synthase efficiency in vivo ( 25 ). This is because the OPH and cysteine concentrations are below 100 μM in the chloroplast compartment ( 32, 33 ).
