“Improved methodology was used to establish that the phosphorylation of a serine located 10 residues from the N-terminus of glycogen synthase (N10) increases from 0.12 mol.mol-1 to 0.54 mol.mol-1 in vivo in response to adrenalin.”
“These results, in conjunction with previous findings, establish that adrenalin inhibits glycogen synthase by increasing the phosphorylation of N7, N10 and three further serines located 30, 34 and 38 residues from the start of the C-terminal CNBr peptide (termed the region C30-C38).”
