ID 4.1.1.93 DE pyrrole-2-carboxylate decarboxylase. CA (1) pyrrole-2-carboxylate + H(+) = 1H-pyrrole + CO2. CA (2) pyrrole-2-carboxylate + H2O = 1H-pyrrole + hydrogencarbonate. CC -!- The enzyme catalyzes both the carboxylation and decarboxylation CC reactions. CC -!- However, while bicarbonate is the preferred substrate for the CC carboxylation reaction, decarboxylation produces carbon dioxide. CC -!- The enzyme is activated by carboxylic acids.
