N-acetylornithine carbamoyltransferase

From Proteopedia

N-acetylornithine carbamoyltransferase complex with acetylornithine, glycerol and sulfate (PDB code 3kzn) Show:Asymmetric Unit Biological Assembly Drag the structure with the mouse to rotate   Export Animated Image Function N-acetylornithine carbamoyltransferase (AOCT) catalyzes the reversible conversion of carbamoyl phosphate and N-acetyl-L-ornithine into N-acetyl-L-citrulline and phosphate. Structural highlights AOCT motif HCLP interacts with the produce acetyl citrulline. The [1]. Water molecules are shown as red spheres.
