The enzyme diaminopropionate ammonia-lyase (EC 4.3.1.15) catalyzes the chemical reaction
This enzyme belongs to the family of lyases, specifically ammonia lyases, which cleave carbon-nitrogen bonds. The systematic name of this enzyme class is 2,3-diaminopropanoate ammonia-lyase (adding water; pyruvate-forming). Other names in common use include diaminopropionatase, ñ,ò-diaminopropionate ammonia-lyase, 2,3-diaminopropionate ammonia-lyase, and 2,3-diaminopropanoate ammonia-lyase. It employs one cofactor, pyridoxal phosphate.
