アミノ酸座位間における共進化に基づく残基間コンタクト予測：タンパク質立体構造予測にむけて

抄録

Residue-residue interactions that fold a protein into a unique three-dimensional structure and make it play a specific function put structural and functional constraints in varying degrees on each residue site. Coevolution between closely-located sites caused by such selective constraints is recorded in amino acid orders of homologous sequences and also in the evolutionary trace of amino acid substitutions. A challenge for predicting residue contacts through coevolving site pairs is to extract direct dependences between sites by removing phylogenetic correlations and indirect dependences through other residues within a protein or even through other molecules. Recent attempts, particularly by detecting co-substitutions, are reviewed.
