- g. acyltransferase an enzyme catalyzing the reversible transfer of an acyl group from acyl-CoA to g., producing free coenzyme A and N-acylglycine; a step in a detoxification pathway.
- g. amidinotransferase an enzyme catalyzing the transfer of an amidine group from l-arginine to g., forming guanidinoacetate and l-ornithine; an important reaction in creatine biosynthesis; it can also act on canavanine. SYN: g. transamidinase.
- g. betaine SYN: betaine.
- g. cleavage complex a complex of several proteins that catalyze the reversible reaction of g. with tetrahydrofolate to produce CO2, NH3, and N5,N10-methylenetetrahydrofolate; a deficiency of this enzyme (or one of its subunits) will result in nonketotic hyperglycinemia. SYN: g. synthase.
- g. dehydrogenases enzymes that catalyze the conversion of g. to glyoxylate and ammonia, using either NAD+ or ferricytochrome c.
