IUBMB Enzyme Nomenclature

EC 4.1.1.93

Accepted name: pyrrole-2-carboxylate decarboxylase

Reaction: (1) pyrrole-2-carboxylate = pyrrole + CO2
(2) pyrrole-2-carboxylate + H2O = pyrrole + HCO3-

Systematic name: pyrrole-2-carboxylate carboxy-lyase

Comments: The enzyme catalyses both the carboxylation and decarboxylation reactions. However, while bicarbonate is the preferred substrate for the carboxylation reaction, decarboxylation produces carbon dioxide. The enzyme is activated by carboxylic acids.
