Other Details ATOMIC COORDINATES FOR GP6, GP15, GP16, GP17 WERE OBTAINED FROM PDB FILES 2JES (LEBEDEV ET AL., EMBO J., 2007, 26, 1984), 2KBZ, 2KCA (LHUILLIER ET AL., PROC.NATL.ACAD.SCI. USA, 2009, 106, 8507), 2LFP (CHAGOT ET AL., PROTEINS, 2012, 80, 319), CORRESPONDIGLY, AND DOCKED INTO EM ELECTRON DENSITY MAP USING FLEXIBLE FIT. ATOMIC COORDINATES FOR MISSING DOMAINS OF GP6 AND GP17.1. WERE MODELLED USING I-TASSER PROTEIN STRUCTURE PREDICTION SERVER (Y ZHANG, BMC BIOINFORMATICS, 2008, 9, 40) AND DOCKED INTO EM ELECTRON DENSITY MAP USING FLEXIBLE FIT. SUBMISSION BASED ON EXPERIMENTAL DATA FROM EMDB EMD-2994. (DEPOSITION ID: 13332).
