I DO NOT REMEMBER WHY WE DECIDED TO REMARK 999 ASSIGN THE ARG NAME TO THIS RESIDUE IN THE HIGH-RESOLUTION REMARK 999 STRUCTURE (GIVEN THAT NO DENSITY COULD BE OBSERVED FOR THE SIDE REMARK 999 CHAIN BEYOND THE CB). MOREOVER, IF THERE IS NO ROOM FOR THE REMARK 999 ACCOMODATION OF AN ARG SIDE CHAIN, IT IS WELL POSSIBLE THAT AN REMARK 999 ALA DOES REALLY OCCUR AND THAT THE ARG COMES FROM A SEQUENCING REMARK 999 MISTAKE (OR A SUBSTITUTION DURING THE CLONING PROCEDURE IN THE REMARK 999 PLASMID(S) USED FOR RECOMBINANT EXPRESSION). I DO NOT KNOW REMARK 999 WHETHER AN ANALYSIS OF THE AA COMPOSITION WAS EVER PERFORMED ON REMARK 999 THE RECOMBINANT PROTEIN USED FOR CRYSTALLOGRAPHY.
