ID 3.7.1.23 DE maleylpyruvate hydrolase. CA 3-maleylpyruvate + H2O = H(+) + maleate + pyruvate. CC -!- The enzyme, characterized from the bacterium Pseudomonas alcaligenes CC NCIMB 9867, catalyzes the hydrolysis of 3-maleylpyruvate, the ring- CC cleavage product of gentisate. CC -!- The enzyme can also act on a number of maleylpyruvate derivatives, CC such as (2E)-2-methyl-4,6-dioxohept-2-enedioate and (2E)-3-methyl- CC 4,6-dioxohept-2-enedioate. CC -!- May be identical to EC 3.7.1.5. DR Q0QFQ3, HBZF_PSEAC ; //
