Details

IN THE PDB FILE THE 35 SUBUNITS MODELED ARE REPRESENTED AS CHAINS NUMBERED FROM A-Z, a-i. THE NOTATION WE USED IN THE PAPER FOR DESCRIBING THE CAPSID ARRANGEMENT IS BASED ON THE PENTAMER SYMMETRY; EACH SUBUNIT PNM IS GIVEN TWO INDICES, WHERE THE INDEX N INDICATES THE PENTAMER NUMBER (N BETWEEN 1-7 WHERE N=1 CORRESPONDS TO THE C-TERMINAL PART) AND M INDICATES THE IDENTITY OF THE SUBUNIT WITHIN EACH PENTAMER(M=1-5). THE TRANSFORMATION FROM THE PAPER'S NOTATION TO THE RESPECTIVE PDB CHAINS IS AS FOLLOWS: P11 J P12 K P13 L P14 M P15 N P21 O P22 P P23 Q P24 R P25 S P31 T P32 U P33 V P34 W P35 X P41 Y P42 Z P43 a P44 b P45 c P51 d P52 e P53 f P54 g P55 h P61 i P62 A P63 B P64 C P65 D P71 E P72 F P73 G P74 H P75 I
