Entrez Gene Summary for GULOP Gene. This gene is nonfunctional in humans and other primates. In most mammalian species the corresponding gene encodes L-gulono-gamma-lactone oxidase which catalyzes the last step of ascorbic acid biosynthesis.The human gene is a remnant that lacks five of twelve exons found in functional rodent genes.The loss of enzyme activity results in hypoascorbemia or the inability to synthesize vitamin C.

L-gulonolactone oxidase (GULO), the final enzyme in the biosynthetic pathway of ascorbic acid (vitamin C), is a subject that comes up often in discussions of common ancestry.
