This reaction serves as the major source of one-carbon groups required for the biosynthesis of purines, thymidylate, methionine, and other important biomolecules. Also exhibits THF-independent aldolase activity toward beta-hydroxyamino acids, producing glycine and aldehydes, via a retro-aldol mechanism. | Threonine deaminase (ilvA); Catalyzes the anaerobic formation of alpha-ketobutyrate and ammonia from threonine in a two-step reaction.
