THE NUMBER OF ATOMS IN THIS STRUCTURE EXCEEDS THE MAXIMUM ALLOWED BY THE PDB FORMAT. IT HAS THEREFORE BEEN SPLIT ACROSS TWO PDB ENTRIES: 2BLD CONTAINS THE PENTON BASE, 2BVI CONTAINS THE FOUR UNIQUE COPIES OF THE HEXON. THE COMPLETE CAPSID CAN BE GENERATED BY APPLYING ICOSAHEDRAL SYMMETRY OPERATORS TO THE COORDINATES IN THE TWO ENTRIES AND THEN COMBINING THE RESULTING CAPSID FRAGMENTS. THE PENTON BASE COMPRISES CHAINS A,B,C,D,E,S,T,U,V AND W AND MUST BE TRANSFORMED BY 12 SPECIFIC MATRICES DEFINED IN REMARK 350. THE HEXONS COMPRISE CHAINS F,G,H,I,J,K,L M,N,O,P AND Q AND MUST BE TRANSFORMED BY ALL ICOSAHEDRAL OPERATORS.
