Energetics of S-adenosylmethionine synthetase catalysis.

Abstract

S-adenosylmethionine synthetase (ATP:L-methionine S-adenosyltransferase) catalyzes the only known route of biosynthesis of the primary biological alkylating agent. The internal thermodynamics of the Escherichia coli S-adenosylmethionine (AdoMet) synthetase catalyzed formation of AdoMet, pyrophosphate (PP(i)), and phosphate (P(i)) from ATP, methionine, and… (More)
