IntEnz Enzyme Nomenclature
EC 4.1.3.24

Names

Accepted name:
malyl-CoA lyase
Other names:
malyl-coenzyme A lyase
(3S)-3-carboxy-3-hydroxypropanoyl-CoA glyoxylate-lyase
mclA (gene name)
mcl1 (gene name)
(3S)-3-carboxy-3-hydroxypropanoyl-CoA glyoxylate-lyase (acetyl-CoA-forming)
L-malyl-CoA lyase
Systematic name:
(S)-malyl-CoA glyoxylate-lyase (acetyl-CoA-forming)

Reactions

Comments:

The enzymes from Rhodobacter species catalyse a step in the ethylmalonyl-CoA pathway for acetate assimilation [3,5]. The enzyme from halophilic bacteria participate in the methylaspartate cycle and catalyse the reaction in the direction of malyl-CoA formation [6]. The enzyme from the bacterium Chloroflexus aurantiacus, which participates in the 3-hydroxypropanoate cycle for carbon assimilation, also has the activity of EC 4.1.3.25, (3S)-citramalyl-CoA lyase [2,4].
