ONLY REMARK 999 ABOUT HALF OF THIS DOMAIN WAS VISIBLE IN THE ELECTRON REMARK 999 DENSITY MAP, AND WHAT CAN BE SEEN IS AMBIGUOUS DUE TO REMARK 999 TOPOLOGY AND CONNECTIVITY ISSUES. FOR THIS REASON, REMARK 999 RESIDUES BEGINNING AT 901 ARE LABELED AS UNKNOWN (UNK). REMARK 999 EACH FRAGMENT OF UNKNOWN RESIDUES HAS BEEN ASSIGNED REMARK 999 A UNIQUE CHAIN ID. HOWEVER, IT SHOULD BE UNDERSTOOD REMARK 999 THAT ONLY ONE SEQUENCE (RESIDUES 1-740) WAS CRYSTALLIZED.
