3-amino-4-hydroxybenzoate + phosphate + 2 H2O

Streptomyces griseus

A0JC76

the reaction is suggested to take place in several steps. Schiff base formation, double bond migration and dephosphorylation followed by ring opening and closing to form a pyrrolidine ring, and finally dehydration to form the product 3-amino-4-hydroxybenzoate
