ID 1.10.3.15 DE grixazone synthase. CA 2 3-amino-4-hydroxybenzoate + H(+) + N-acetyl-L-cysteine + 2 O2 = CO2 + CA grixazone B + 4 H2O. CC -!- The enzyme, isolated from the bacterium Streptomyces griseus, CC catalyzes an 8 electron oxidation. CC -!- Activation of the enzyme requires a copper chaperone (GriE). CC -!- It also acts on 3-amino-4-hydroxybenzaldehyde, giving grixazone A. CC -!- The second aldehyde group is presumably lost as formate. CC -!- The enzyme also catalyzes the reaction of EC 1.10.3.4.
