GCSH_STAA9 gcvH Is also involved in protein lipoylation via its role as an octanoyl/lipoyl carrier protein intermediate (By similarity). The glycine cleavage system catalyzes the degradation of glycine. The H protein shuttles the methylamine group of glycine from the P protein to the T protein (By similarity). 126 Glycine cleavage system H protein MAVPNELKYSKEHEWVKVEGNVATIGITEYAQSELGDIVFVELPETDDEINEGDTFGSVESVKTVSELYAPISGKVVEVNEELEDSPEFVNESPYEKAWMVKVEISDESQLEALLTAEKYSEMIGE SaurJH9_0832 Octanoyl/lipoyl carrier protein
