Description 4-amino-4-deoxychorismate lyase
Alternative names 4-amino-4-deoxychorismate pyruvate-lyase;
Aminodeoxychorismate lyase;
ADC lyase.
Catalyzed reaction 4-amino-4-deoxychorismate = 4-aminobenzoate + pyruvate
Cofactor Pyridoxal-phosphate.
Comments Forms part of the folate biosynthesis pathway.
Acts on 4-amino-4-deoxychorismate, the product of EC, aminodeoxychorismate synthase, to form p-aminobenzoate.
At least three different subgroups of enzymes with this activity appear to exist. These enzymes all belong to the fold-type IV group, but show very limited sequence similarity to each other.
