| Other name(s): |
citramalyl coenzyme A lyase (ambiguous); (+)-CMA-CoA lyase; (3S)-citramalyl-CoA pyruvate-lyase; Mcl (ambiguous); citramalyl-CoA lyase (ambiguous) |
| Systematic name: |
(3S)-citramalyl-CoA pyruvate-lyase (acetyl-CoA-forming) |
| Comments: |
Requires Mg2+ ions for activity [3]. The enzyme from the bacterium Clostridium tetanomorphum is a component of EC 4.1.3.22, citramalate lyase [2]. It also acts on (3S)-citramalyl thioacyl-carrier protein [2]. The enzyme from the bacterium Chloroflexus aurantiacus also has the activity of EC 4.1.3.24, malyl-CoA lyase [3]. It has no activity with (3R)-citramalyl-CoA (cf. EC 4.1.3.46, (R)-citramalyl-CoA lyase) [3]. |
