Comments [?]

Function Catalyzes the carbon skeleton rearrangement of L-glutamate to L-threo-3-methylaspartate ((2S,3S)-3-methylaspartate).
Catalytic activity L-threo-3-methylaspartate = L-glutamate.
Cofactor adenosylcob(III)alamin
Pathway Amino-acid degradation; L-glutamate degradation via mesaconate pathway; acetate and pyruvate from L-glutamate: step 1/4.
Subunit Heterotetramer composed of 2 epsilon subunits (GlmE) and 2 sigma subunits (GlmS). GlmE exists as a homodimer and GlmS as a monomer.
Similarity Belongs to the methylaspartate mutase GlmS subunit family.
