Glycine amindinotransferase, localized to the mitochondrial intermembrane space, catalyzes the reaction of arginine and glycine to form guanidinoacetate and ornithine. The active form of the enzyme is a dimer (Humm et al. 1997 {EMBO J]; Humm et al 1997 [Biochem J]). Its function in vivo has been confirmed by molecular and biochemical studies of patients deficient in the enzyme (Item et al. 2001).
