Ornitin karbamoiltransferaza (EC 2.1.3.3, citrulinska fosforilaza, ornitinska transkarbamilaza, OTC, karbamilfosfat-ornitinska transkarbamilaza, L-ornitinska karbamoiltransferaza, L-ornitinska karbamiltransferaza, L-ornitinska transkarbamilaza, ornitinska karbamiltransferaza) je enzim sa sistematskim imenom karbamoil-fosfat:L-ornitin karbamoiltransferaza.[1][2][3][4] Ovaj enzim katalizuje sledeću hemijsku reakciju
- karbamoil fosfat + L-ornitin fosfat + L-citrulin
Ovaj biljni enzim takođe katalizuje reakcije EC 2.1.3.6, putrescin karbamoiltransferaze, EC 2.7.2.2, karbamatne kinaze i EC 3.5.3.12 agmatinske deiminaze. On deluje kao putrescinska sintaza, koji konvertuje agmatin [(4-aminobutil)guanidin] i ornitin u putrescin i citrullin, respektivno.
