>TIGR02146 LysS_fung_arch homocitrate synthase; InterPro: IPR011872 This entry includes the yeast LYS21 gene which carries out the first step of the alpha-aminoadipate (AAA) lysine biosynthesis pathway. A related pathway is found in Thermus thermophilus . This enzyme is closely related to 2-isopropylmalate synthase (LeuA) and citramalate synthase (CimA), both of which are present in the euryarchaeota. Some archaea have a separate homocitrate synthase (AksA) which also synthesizes longer homocitrate analogs .; GO: 0046912 transferase activity transferring acyl groups acyl groups converted into alkyl on transfer, 0019752 carboxylic acid metabolic process.
