I have compiled a crossreference of the Brookhaven Protein Data Bank
files which may be of use to others.  If you find errors in this
listing please let me know.

   This file is an annotation of all of the Brookhaven Protein Data
   Bank files with actual coordinates.  (The files beginning with
   pdb0 have been omitted until full coordinates are available.)
   The information has been taken from the Brookhaven Protein Data
   Bank and from original papers by authors listed in those files.
   Responsibility for the accuracy of the information is LLW's,
   who would welcome reports of errors and suggestions to extend
   the usefulness of the information.  This information is provided
	for your use and no warranty about the correctness of the infor-
	mation is made.

/* 
   Description of Entries:

   The header line begins with the common name for the protein or 
   other molecule(s) contained in the file.I have tried to use 
   the most commonly accepted names, but in several cases, especially
   the immunoglobulin files, this has been difficult. 

   The molecule name is followed by its source.  This is the
   source of the original sequence.In several cases a protein
   is actually expressed in another organism, such as E. coli,
   but this is not noted in this file.

    DUP = duplicate entry.  This file is also listed for
         another protein or other molecule.  (E.g. the Eglin C
         and subtilisin complex is listed under both headers.)

   The file names from the Brookhaven Protein Data Bank have been
   abbreviated.  Where Brookhaven names the files pdbXXXX.ent, 
	the files are referred to here solely by the XXXX part.  Files 
	with a "w" appended to their names are files that I have 
	modified to make a "complete" protein, i.e., if the protein 
	is a tetramer and only two of the chains are given in the 
	original file, the new file would contain the tetramer and 
	conversely, if the original file contains two chains and 
   the protein is a monomer, this file contains a single chain.  
   These files are not publicly available at present.   

   The columns following the PDB file name indicate the resolution
   for the x-ray data.  If the file is an NMR file, "NMR" is in
   this field, since resolution is not applicable for these.  "CA"
   indicates that the entry contains coordinate information only
   for the alpha carbons.  "UNK" means the amino acid sequence
   is unknown.

   The body of the entry indicates how many chains are in the
   "complete" molecule (see below), how many chains are included
   in the entry, and any other information that helps distinguish
   that specific entry from another similar entry.  I have also
   included any information I had that could help in interpreting
   the data in the entry.In particular, I have attempted to
   include any possible differences between the crystallographic
   data and what is thought to be the active, "solution" structure
   of the molecule.  I am currently working on including information
	about ions and crystallization conditions, but this information
	should be considered incomplete.

/*   

   "Correct" proteins are either the complete protein as seen in
   the pictures accompanying the original literature or, failing
   this, a protein that "looks ok" and which can be generated by
   both my program and Insight (Biosym) to look the same.  Failing 
   both of these, a correct protein is as close as I could come to 
   what I think is correct.  If it is not, PLEASE let me know.  
   
   The "correct" proteins were generated by one of several possible 
   methods:

   1)  If there was a matrix given in the data file itself which
   produced a "correct" protein, this was used.

   2)  If there was no applicable matrix, or if the matrix did
   not generate a correct protein, the International Table for
   Crystallography matrices were used.  If possible, these were 
   checked against the matrices and proteins produced by Insight 
   (Biosym).  Insight (Biosym) can do symmetry operations in its 
   Assembly module under the Symmetry command.  The program uses 
   a 4 X 4 matrix and is thus not the same as the program I use 
   to make symmetry related protein chains.  I use a 3 X 4 matrix. 

   I prefer my program for two reasons -- the atom numbering used 
	in the original file is retained and the symmetry related 
	chains are numbered 10000 more than the original atoms.  This 
	requires renumbering when there are several symmetry operations 
	performed, but it makes generating CONECT records much easier.

   3wga 1.8    dimer - 2 chains given; isolectin 2?
   7wga 2.0    dimer - 2 chains given; isolectin 1
   9wga 1.8    dimer - 2 chains given; supersedes 3wga; isolectin 2; this
               molecule does NOT look correct - too much empty space; 
               orientation of different domains seems wrong.  Made dimers 
               by using each monomer and transforming acc to C2 matrix - 
               9wgaAC.pdb looks better and looks like one of dimers made by 
               Insight.  9wgaBD.pdb has (at least) translational problems.  
               Reordered lit - no good picture of real structure.
