Other Details TO ACCOUNT FOR THE FACT THAT HELIX ALPHA4 IS LONGER IN OUR RECONSTRUCTION THAN IN THE AVAILABLE ADP CRYSTAL STRUCTURES, WE MODELLED 7 HELICAL TURNS OF HELIX ALPHA4 ( RESIDUES D279-E304), AS OBSERVED IN THE ENTRY 3HQD. THE N- TERMINAL SEQUENCE WAS MODELLED USING MODELLER. SUBMISSION BASED ON EXPERIMENTAL DATA FROM EMDB EMD-2537. (DEPOSITION ID: 12202).
