== Function ==
[https://www.uniprot.org/uniprot/HOSA_THET2 HOSA_THET2] 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).<ref>PMID:12095615</ref> <ref>PMID:19996101</ref> <ref>PMID:9868782</ref>
