>The objective of pre-release is to make pending entries readily available to

>limited number of PDB record types useful in identifying the deposition. All
>other details will be provided when the standard release entry becomes
>available.
> 
>Pre-release entries may not fully conform to the specifications given in the
>Protein Data Bank Atomic Coordinate and Bibliographic Entry Format Description.
>For example, residue and atom names for heterogens may not be in the PDB
>standard format. Changes to these names may therefore occur when the standard
>release entry becomes available.
> 
>The following checks have been made for all pre-release entries:
> 
>	1.Amino acid sequence for proteins compared to the non-redundant
>	sequence database using the GENINFO computing environment 
>	(National Center for Biotechnology Information, 
>	National Library of Medicine).
> 
>	2.Stereochemistry including:
> 
>		Bond distances and angles
>		Distortions of planar groups
>		Ramachandran plot
> 
>	3.Crystal packing.
> 
>A visual check of each entry has been made using MidasPlus (Computer Graphics
>Laboratory, University of California, San Francisco). 
> 
>In the future, submitted coordinate data sets will be made available through
>pre-release immediately after the above checks have been made and once
>depositors have given their approval to release the entry.
