Maleamate amidohydrolase

Maleamate amidohydrolase (EC 3.5.1.107, NicF) is an enzyme with systematic name maleamate amidohydrolase.^[1] This enzyme catalyses the following chemical reaction

maleamate + H₂O

\rightleftharpoons

maleate + NH₃

The reaction is involved in the aerobic catabolism of nicotinic acid.
