Flux through glycine cleavage system in isolated hepatocytes: effects of glucagon, cAMP, and calcium.


The hepatic glycine cleavage system (GCS) is the principal route for the metabolism of glycine in mammals. Flux through the GCS in isolated rat hepatocytes was stimulated by about 100% by glucagon (10(-7) M), forskolin (10(-4) M), and dibutyryl cAMP (10(-4) M). The stimulation of flux through the GCS by these agents was accompanied by marked elevation of… (More)
