SIGMA, JURNAL SAINS DAN TEKNOLOGI, Vol. 13, No. 1 Januari 2010, ABSTRAK : Molecular Biology is advancing through the protein-protein interaction studies. Its wet experiment has generated a massive amount of data. Bioinformatics was set up for converting those data info useful information. Protein-protein interaction wet experiment was a long and expensive labors. Bioinformatics are here to remedy those labors. Online experiments in protein-protein interaction database are possible. The available databases are Inter Pare, Clus Pro, and PROTORP. InterPare is an open and public database server for protein interaction interface information. ...
