Other Details THE COORDINATES IN THIS ENTRY WERE GENERATED BY MANUAL DOCKING OF THE STRUCTURE OF THE ESCHERICHIA COLI 30S RIBOSOMAL SUBUNIT (2AVY) AND SALMONELLA TYPHYMURIUM (2RCN) INTO THE DENSITY MAP OF THE ESCHERICHIA COLI 30S_YJEQ COMPLEX GENERATED BY CRYO-ELECTRON MICROSCOPY. THE YEJQ PROTEIN WAS FITTED AS THREE SEPARATE DOMAINS: THE OB-FOLD, THE GTPASE DOMAIN, AND THE ZINC-FINGER DOMAIN. THE PROTEIN DATA BANK CONVENTIONS REQUIRE TO ENTER INFORMATION ABOUT THE UNIT CELL, CRYSTAL DATA AND COORDINATE SYSTEM. THESE INFORMATION IS MEANINGLESS IN THIS ENTRY. SUBMISSION BASED ON EXPERIMENTAL DATA FROM EMDB EMD-1895.
