Find PDB structures and Computed Structure Models (CSM) by combining queries from tools in this suite: Attribute Search, Sequence Similarity, Sequence Motif, 3D Similarity, and 3D Motif with 'AND' logic.
RESIDUES 134-142 ARE MISSING FROM THE SEQUENCE. THE 31-MER CAN BE GENERATED BY APPLYING 31-FOLD ROTATIONAL SYMMETRY

METHOD--THE CRYSTAL STRUCTURE OF PERFRINOGLYSIN O (1PFO, ROSSJOHN ET AL., 1998,
CELL 89, 685)WAS PLACED INTO THE CRYO-EM DENSITY MAP (EMD-1106). THE ALPHA
CARBON TRACE OF PERFRINGOLYSIN 0 WAS MANUALLY POSITIONED INTO THE CRYO-EM
DENSITY CORRESPONDING TO THE POSITION OF ONE SUBUNIT. THE BEST FIT WAS OBTAINED
BY SEPARATING THE MONOMER INTO TWO RIGID BODIES- DOMAINS 1-3 (36-390) AND
DOMAIN 4 (391-500). THE COMPLETE OLIGOMER (31-MER) WAS GENERATED AND CHECKED
FOR CLOSE CONTACTS BOTH BY EYE AND USING THE CCP4 PROGRAM CONTACT.
