摘要：

Glutamate racemase of Pediococcus pentosaceus catalyzes the alpha,beta-elimination of L-serine O-sulfate to produce a pyruvate concomitantly with an irreversible inactivation of the enzyme. alpha,beta-Elimination and inactivation reactions proceed through a common intermediate. L-Serine O-sulfate serves as a suicide substrate of the enzyme.
