bookmark LinkProt A database of proteins with topological links. LinkProt collects information about protein chains and complexes that form links. LinkProt detects deterministic links (with loops closed by cysteine), and determines likelihood of formation of links in networks of protein chains called MacroLinks. Links are presented graphically in an intuitive way, using tools that involves surfaces of minimal area spanned on closed loops. The database presents extensive information about biological functions of proteins with links and enables users to analyze new structures.
