2.8.3.26

Accepted name:

succinyl-CoA:mesaconate CoA transferase

Reaction:

succinyl-CoA + mesaconate = 2-methylfumaryl-CoA + succinate

Glossary:

2-methylfumaryl-CoA = (E)-3-carboxy-2-methylprop-2-enoyl-CoA
mesaconate = 2-methylbut-2-enedioic acid

Other name(s):

mct (gene name)

Systematic name:

succinyl-CoA:mesaconate CoA transferase

Comments:

The enzyme participates in the methylaspartate cycle, an anaplerotic pathway that operates in some members of the haloarchaea and forms malate from acetyl-CoA.
