Methylaspartate ammonia-lyase EC:4.3.1.2 catalyses the second step of fermentation of glutamate. It is a homodimer. This family represents the C-terminal region of Methylaspartate ammonia-lyase and contains a TIM barrel fold similar to the Pfam:PF01188. This family represents the catalytic domain and contains a metal binding site [2].
