Methionine Biosynthesis

Escherichia coli (strain K12)
This pathway shows the biosynthesis of methionine, which is an energy-costly process. Lysine biosynthesis produces L-Aspartate-semialdehyde, which later on is catalyzed to L-homoserine by bifunctional aspartokinase (also named homoserine dehydrogenase) 1 and 2. Homoserine is then activated by O-succinylation to form O-succinyl-L-homoserine via homoserine O-succinyltransferase (metA). Combining with L-cysteine, O-succinyl-L-homoserine form L-cystathionine and succinic acid by cystathionine gamma-synthase (metB). Cleavage of L-cystathionine by cystathionine beta-lyase (metC) or Protein MalY(as ) generates two small molecules: homocysteine and 2-aminoprop-2-enoate. Methionine synthase(MetH) or 5-methyltetrahydropteroyltriglutamate--homocysteine methyltransferase(MetE) will catalyzehomocysteine to form the final product: methionine. In E.coli, MetH can only function with existence of cobalamin (Vitamin B12), which can be available in the guy; without cobalamin, MetE will not be repressed so that it will catalyze the methionine. Methionine can be transported out of cell (into periplasmic space) by leucine efflux transporter.
