In enzymology an ornithine cyclodeaminase (EC 4.3.1.12) is an enzyme that catalyzes the chemical reactionL-ornithine L-proline + NH3Hence this enzyme has one substrate L-ornithine and two products L-proline and 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-ornithine ammonia-lyase (cyclizing; L-proline-forming).
