Carbamoyl serine ammonia lyase

In enzymology, a carbamoyl-serine ammonia-lyase (EC 4.3.1.13) is an enzyme that catalyzes the chemical reaction

Thus, the two substrates of this enzyme are O-carbamoyl-L-serine and H₂O, whereas its 3 products are pyruvate, NH₃, and CO₂.

This enzyme belongs to the family of lyases, specifically ammonia lyases, which cleave carbon-nitrogen bonds. The systematic name of this enzyme class is O-carbamoyl-L-serine ammonia-lyase (decarboxylating pyruvate-forming). Other names in common use include O-carbamoyl-L-serine deaminase, carbamoylserine deaminase, and O-carbamoyl-L-serine ammonia-lyase (pyruvate-forming). It employs one cofactor, pyridoxal phosphate.
