Pyruvate carboxylase is a biotin-dependent enzyme in which the biotin is carboxylated by a putative carboxyphosphate intermediate that is formed in a reaction between ATP and bicarbonate. The resultant carboxybiotin then transfers its carboxyl group to pyruvate to form oxaloacetate. In the Bacillus...
