WHERE THESE ASSIGNMENTS COME FROM

These domain assignments are primarily taken from the literature. Where this stategy was inappropiate (e.g. not defined in publication), domain assignments were by visual inspection. These assignments were made for a non-redundent representative set of the April 1996 Brookhaven protein data bank (PDB). Domain assignments for protein homologous to this set were assigned by projecting the author assignment onto a multiple sequence alignment.

We prefer to use authors' assignment of domains, where possible, as they generally incorporate knowledge from a variety of sources in their decision making process. For example, structural similarity between proteins and identification of functional modules augment consideration of distinct spatial segments. To date, neither visual inspection nor computer algorithms incorporate all of these concepts.

The non-redundent set was created by using BLASTP and complete linkage cluster analysis to created groupings of structures all having BLAST probabilities of 10e-10 or lower. Alignments of all sequences in these sets were calculated using the AMPS package.


VISUALISATION OF DOMAIN ASSIGNMENTS

Our domain assignments can be viewed using Rasmol or PREPI (Silicon Graphics Computers Only). The domain assignments are shown using different colour schemes.
