Serine sulfate ammonia lyase

In enzymology, a serine-sulfate ammonia-lyase (EC 4.3.1.10) is an enzyme that catalyzes the chemical reaction

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

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-serine-O-sulfate ammonia-lyase (pyruvate-forming). This enzyme is also called (L-SOS)lyase.
