Chains	Enzyme Name	Description	Catalytic Residues
A, B	methylaspartate mutase M-CSA #63	This vitamin B12 dependent enzyme catalyses the carbon skeleton rearrangement of L-glutamate to L-threo-3-methylaspartate ((2S,3S)-3-methylaspartate). It is involved in the subpathway that synthesises acetate and pyruvate from L-glutamate.
