Definition of cimA

• Curated proteins or TIGRFams with EC 2.3.1.182
• Curated proteins or TIGRFams with EC 2.3.3.21
• UniProt sequence Q8F3Q1: RecName: Full=(R)-citramalate synthase CimA {ECO:0000305}; EC=2.3.3.21 {ECO:0000269|PubMed:15292141, ECO:0000269|PubMed:18498255, ECO:0000269|PubMed:19351325}; AltName: Full=LiCMS {ECO:0000303|PubMed:18498255};
• UniProt sequence D4GSQ2: SubName: Full=2-isopropylmalate synthase / (R)-citramalate synthase {ECO:0000313|EMBL:ADE04954.1}; EC=2.3.1.182 {ECO:0000313|EMBL:ADE04954.1}; EC=2.3.3.13 {ECO:0000313|EMBL:ADE04954.1};
• Comment: MetaCyc L-isoleucine biosynthesis II describes the formation of 2-oxobutanoate via citramalate. The other steps are the same (although it gives a different EC number for ilvC because of different cofactor preference) The citramalate synthase from Leptopsira interrogans (LA_2350, NP_712531, or Q8F3Q1) has been characterized biochemically but is not in the curated databases, see PMID:18498255 The putative citramalate synthase HVO_0644 (D4GSQ2) from Haloferax volcanii is required for isoleucine biosynthesis, see PMC4300041.
