The enzyme methylaspartate ammonia-lyase (EC 4.3.1.2) catalyzes the chemical reaction
- L-threo-3-methylaspartate mesaconate + NH3
This enzyme belongs to the family of lyases, specifically ammonia lyases, which cleave carbon-nitrogen bonds. The systematic name of this enzyme class is L-threo-3-methylaspartate ammonia-lyase (mesaconate-forming). Other names in common use include β-methylaspartase, 3-methylaspartase, and L-threo-3-methylaspartate ammonia-lyase. This enzyme participates in c5-branched dibasic acid metabolism and nitrogen metabolism. It employs one cofactor, cobamide.
