A protein chain can correspond to a monomeric protein or it can form, together with other chains, oligomeric assemblies, which can be either homo-oligomers or hetero-oligomers. In the latter case, the three-dimensional structure of the single protein chain is unlikely to be determined, since it will probably be difficult to express and crystallize. A computational method is presented here that allows one to predict if a chain participates in hetero-oligomeric assemblies, on the basis of its amino acid composition, with accuracy close to 80%. Such a technique should improve the success rate of structural biology projects.

Abstract
A protein chain can correspond to a monomeric protein or it can form, together with other chains, oligomeric assemblies, which can be either homo-oligomers or hetero-oligomers. In the latter case, the three-dimensional structure of the single protein chain is unlikely to be determined, since it will probably be difficult to express and crystallize. A computational method is presented here that allows one to predict if a chain participates in hetero-oligomeric assemblies, on the basis of its amino acid composition, with accuracy close to 80%. Such a technique should improve the success rate of structural biology projects.File in questo prodotto:
