Ornithine → Putrescine + CO(2)details
Ornithine → Putrescine + Carbon dioxidedetails
General function:
Involved in arginase activity
Specific function:
May play a role in the regulation of extra-urea cycle arginine metabolism and also in down-regulation of nitric oxide synthesis. Extrahepatic arginase functions to regulate L-arginine bioavailability to NO synthase. Since NO synthase is found in the penile corpus cavernosum smooth muscle, the clitoral corpus cavernosum and the vagina, arginase II plays a role in both male and female sexual arousal. It is therefore a potential target for the treatment of male and female sexual arousal disorders.
Gene Name:

Reactions
L-Arginine + Water → Ornithine + Ureadetails
