Knowledge-based model building of proteins: concepts and examples.
J.Bajorath, R.Stenkamp, A.Aruffo.
We describe how to build protein models from structural templates. Methods to identify structural similarities between proteins in cases of significant, moderate to low, or virtually absent sequence similarity are discussed. The detection and evaluation of structural relationships is emphasized as a central aspect of protein modeling, distinct from the more technical aspects of model building. Computational techniques to generate and complement comparative protein models are also reviewed. Two examples, P-selectin and gp39, are presented to illustrate the derivation of protein model structures and their use in experimental studies.

Secondary-structureelments in MBP arelabeled.Residuescon- servedin MBP and P-slectin are boxedandresiduesconsrved in all selectins are shaded. This sequence-structurealignment provided the basis for comparative model building of the P-selectinligand-binding domain. B: Model structure of li- gand-bindng domain of P-selectin.

The calculatedZ-score for the MBPsequence and crystal structure is30.8, the Z-score for the P-selectinsequence and model is 34.9.

The most recent references are shown first. Citation data come partly from CiteXplore and partly from an automated harvesting procedure. Note that this is likely to be only a partial list as not all journals are covered by either method. However, we are continually building up the citation data so more and more references will be included with time. Where a reference describes a PDB structure, the PDB code is shown on the right.
