Homocitrate synthase

UniProtKB accession:  O87198

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Catalyzes the aldol-type condensation of 2-oxoglutarate with acetyl-CoA to yield homocitrate (PubMed:19996101, PubMed:12095615). Carries out the first step of the alpha-aminoadipate (AAA) lysine biosynthesis pathway (PubMed:9868782). To a lesser extent, can also use oxaloacetate in place of 2-oxoglutarate, leading to citrate. Does not display 2-isopropylmalate synthase activity since it cannot use 2-oxoisovalerate (PubMed:12095615).
