Fusarinine C ornithinesterase

In enzymology, a fusarinine-C ornithinesterase (EC 3.1.1.48) is an enzyme that catalyzes the chemical reaction

N₅-acyl-L-ornithine ester + H₂O ⇌ N₅-acyl-L-ornithine + an alcohol

Thus, the two substrates of this enzyme are N5-acyl-L-ornithine ester and H₂O, whereas its two products are N5-acyl-L-ornithine and alcohol.

This enzyme belongs to the family of hydrolases, specifically those acting on carboxylic ester bonds. The systematic name of this enzyme class is N5-acyl-L-ornithine-ester hydrolase. Other names in common use include ornithine esterase, and 5-N-acyl-L-ornithine-ester hydrolase.
