>TIGR00139 h_aconitase homoaconitase; InterPro: IPR004418 Homoaconitase (cis-homoaconitase; 4.2.1.36 from EC) catalyses the dehydration of cis-homoaconitate to homoisocitric acid. It is an enzyme from the alpha-aminoadipate pathway of lysine biosynthesis, and has been identified in higher fungi and several archaea and one thermophilic species of bacteria, Thermus thermophilus . Like aconitase, this enzyme binds a [4Fe-4S]-cluster, and it has a similar domain architecture to aconitase and isopropylmalate isomerase family proteins, although it catalyses a different reaction . Homoaconitase is found in the mitochondria of certain fungi. Information about related proteins can be found at Protein of the Month: Aconitase .; GO: 0004409 homoaconitate hydratase activity, 0051539 4 iron 4 sulfur cluster binding, 0009085 lysine biosynthetic process.
