[Jmol-users] PDB question

[Bob H. <ha...@st...>]

I'm getting an error with

load =1mms

indicating:

structure definition error
 indexStart:129 indexEnd:16

from the header:

SHEET    1   A 3 ILE A   9  PRO A  14  0                                        
SHEET    2   A 3 ILE A  53  VAL A  60 -1  N  ILE A  58   O  ILE A   9           
SHEET    3   A 3 PHE A  66  ILE A  70 -1  N  ILE A  69   O  VAL A  57           
SHEET    1   B 2 GLY A  98  THR A 101  0                                        
SHEET    2   B 2 ILE A 137  VAL A  24  1  N  GLU A 138   O  GLY A  98           
SHEET    1   C 2 GLY B  98  VAL B 100  0                                        
SHEET    2   C 2 ILE B 137  VAL B 139  1  N  GLU B 138   O  GLY B  98           


Is that just a PDB file error for that next-to-last SHEET? 
How can its "N-terminus" be [ILE]137 and then extend to [VAL]24?

Does anyone know how these secondary structures are determined?

Bob
