General Information

General Information Comment Organism
physiological function the pL-dependent activity of MDO can be rationalized assuming a diprotic enzyme model in which three ionic forms of the enzyme are present [cationic, E(z+1), neutral, Ez, and anionic, E(z-1)]. The activities observed for substrates 3-mercaptopropanoate and cysteine appear to be dominated by electrostatic interactions within the enzymatic active site Azotobacter vinelandii
