Figure 1From: Determination of key enzymes for threonine synthesis through in vitro metabolic pathway analysisThreonine synthesis pathway from aspartate in E. coli. The reactions are catalyzed by aspartate kinase (ThrA, MetL, LysC), aspartate semialdehyde dehydrogenase (Asd), homoserine dehydrogenase (ThrA), homoserine kinase (ThrB) and threonine synthase (ThrC). ASA aspartic β-semialdehyde, aspartyl-P β-aspartyl phosphate.Back to article page
