Finding protein-protein interaction patterns by contact map matching. Repositório Alice
MELO, R. C.; RIBEIRO, C.; MURRAY, C. S.; VELOSO, C. J. M.; SILVEIRA, C. H. da; NESHICH, G.; MEIRA JUNIOR, W.; CARCERONI, R. L.; SANTORO, M. M..
We propose a novel method for defining patterns of contacts present in protein-protein complexes. A new use of the traditional contact maps (more frequently used for representation of the intra-chain contacts) is presented for analysis of inter-chain contacts. Using an algorithm based on image processing techniques, we can compare protein-protein interaction maps and also obtain a dissimilarity score between them. The same algorithm used to compare the maps can align the contacts of all the complexes and be helpful in the determination of a pattern of conserved interactions at the interfaces. We present an example for the application of this method by analyzing the pattern of interaction of bovine pancreatic trypsin inhibitors and trypsins, chymotrypsins,...

Zinc fingers: DNA binding and protein-protein interactions Biol. Res.
LEON,OSCAR; ROTH,MONICA.
The zinc finger domain is a very ubiquitous structural element whose hallmark is the coordination of a zinc atom by several amino acid residues (cysteines and histidines, and occasionally aspartate and glutamate). These structural elements are associated with protein-nucleic acid recognition as well as protein-protein interactions. The purpose of this review is to examine recent data on the DNA and protein binding properties of a few zinc fingers whose three dimensional structure is known
