Remark 999 | SEQUENCE RESULTS ARE FROM DAY FOURTEEN OF CRYSTALLIZATION. IN THE COORDINATE RECORDS SCY/CYS 111 ...SEQUENCE RESULTS ARE FROM DAY FOURTEEN OF CRYSTALLIZATION. IN THE COORDINATE RECORDS SCY/CYS 111 ISOFORMS ARE MODELED AS ALTERNATE CONFORMERS. BECAUSE OF THE FORMAT RESTRICTIONS ONLY SCY 111 ISOFORM IS REPRESENTED IN THE SEQUENCE RECORDS. |
