2QIU - PubMed Abstract: 
The N-terminal glycine of the A-chain in insulin is reported to be one of the residues that binds to the insulin receptor. Modifications near this region lead to variations in the biological activity of insulin. One such modification viz., an addition of an arginine at the N-terminal A-chain, was reported to possess two-thirds the activity of native insulin ...
