Other name(s): enzyme X; 4-amino-4-deoxychorismate lyase; 4-amino-4-deoxychorismate pyruvate-lyase
Systematic name: 4-amino-4-deoxychorismate pyruvate-lyase (4-aminobenzoate-forming)
Comments: A pyridoxal-phosphate protein. Forms part of the folate biosynthesis pathway. Acts on 4-amino-4-deoxychorismate, the product of EC, aminodeoxychorismate synthase, to form p-aminobenzoate.
