[https://www.uniprot.org/uniprot/MAAL_CITAM MAAL_CITAM] Involved in the methylaspartate cycle. Catalyzes the formation of the alpha,beta-unsaturated bond by the reversible anti elimination of ammonia from L-threo-beta-methylaspartate (L-threo-(2S,3S)-3-methylaspartate) to give mesaconate (By similarity).
