pubmed-article:1656658 | pubmed:abstractText | A method is suggested for evolutionary tree building for proteins with low level of similarity. The degree of similarity is computed by conservative parts for a given family. The method allows to reveal the relationship of amino acid sequences even in cases when conventional techniques yield negative results. Evolutionary tree for signal receptor proteins is built. All the investigated proteins (except STE2) display non-accidental similarity. | lld:pubmed |
