EC | 2.3.1.182 | ||||
Transferred entry: | (R)-citramalate synthase. Now classified as EC 2.3.3.21, (R)-citramalate synthase. | ||||
EC | 2.3.3.21 | ||||
Accepted name: | (R)-citramalate synthase | ||||
Reaction: | acetyl-CoA + pyruvate + H2O = CoA + (2R)-2-hydroxy-2-methylbutanedioate | ||||
Glossary: | (2R)-2-hydroxy-2-methylbutanedioate = (2R)-2-methylmalate = (–)-citramalate 3-methyl-2-oxobutanoate = α-ketoisovalerate 2-oxobutanoate = α-ketobutyrate 4-methyl-2-oxopentanoate = α-ketoisocaproate 2-oxohexanoate = α-ketopimelate 2-oxoglutarate = α-ketoglutarate |
||||
Other name(s): | CimA | ||||
Comments: | One of the enzymes involved in a pyruvate-derived pathway for isoleucine biosynthesis that is found in some bacterial and archaeal species [1,2]. The enzyme can be inhibited by isoleucine, the end-product of the pathway, but not by leucine [2]. The enzyme is highly specific for pyruvate as substrate, as the 2-oxo acids 3-methyl-2-oxobutanoate, 2-oxobutanoate, 4-methyl-2-oxopentanoate, 2-oxohexanoate and 2-oxoglutarate cannot act as substrate [1,2]. | ||||

EC | 2.8.3.20 | ||||
Accepted name: | succinyl-CoA—D-citramalate CoA-transferase | ||||
Reaction: | (1) succinyl-CoA + (R)-citramalate = succinate + (R)-citramalyl-CoA (2) succinyl-CoA + (R)-malate = succinate + (R)-malyl-CoA |
||||
Glossary: | (R)-citramalate = (2R)-2-hydroxy-2-methylbutanedioate (R)-malate = (2R)-2-hydroxybutanedioate (R)-malyl-CoA = (3R)-3-carboxy-3-hydroxypropanoyl-CoA |
||||
Other name(s): | Sct | ||||
Systematic name: | succinyl-CoA:(R)-citramalate CoA-transferase | ||||
Comments: | The enzyme, purified from the bacterium Clostridium tetanomorphum, can also accept itaconate as acceptor, with lower efficiency. | ||||
