or·ni·thine car·ba·mo·yl·trans·fer·ase (orґnĭ-thēn kahr-bam″o-əl-transґfər-ās) [EC 2.1.3.3] an enzyme of the transferase class that catalyzes the carbamoylation of ornithine by carbamoyl phosphate to form citrulline. The reaction occurs in liver mitochondria as part of the urea cycle (see illustration at urea cycle, under cycle). Called also ornithine transcarbamoylase (OTC). Abbreviated OCT.
