Protein name | RecName: Full=N-acetylornithine carbamoyltransferase; EC=2.1.3.9; AltName: Full=N-acetyl-L-ornithine transcarbamylase; Short=AOTCase; Short=Acetylornithine transcarbamylase; |
Gene name | Name=argF'; |
Comments
[?]
FUNCTION | Catalyzes the transfer of the carbamoyl group from carbamoyl phosphate to the delta-amino group of N(2)-acetyl-L-ornithine to produce N(2)-acetyl-L-citrulline. This is a step in an alternative arginine biosynthesis pathway. |
CATALYTIC ACTIVITY | Reaction=carbamoyl phosphate + N(2)-acetyl-L-ornithine = H(+) + N(2)- acetyl-L-citrulline + phosphate; Xref=Rhea:RHEA:18609, ChEBI:CHEBI:15378, ChEBI:CHEBI:43474, ChEBI:CHEBI:57805, ChEBI:CHEBI:58228, ChEBI:CHEBI:58765; EC=2.1.3.9; PhysiologicalDirection=left-to-right; Xref=Rhea:RHEA:18610; |
PATHWAY | Amino-acid biosynthesis; L-arginine biosynthesis. |
SUBUNIT | Homotrimer. |
SUBCELLULAR LOCATION | Cytoplasm. |
SIMILARITY | Belongs to the aspartate/ornithine carbamoyltransferase superfamily. AOTCase family. |
