Множественное выравнивание совокупности аминокислотных последовательностей на основе вероятностной модели эволюции

The problem of measuring group similarity of amino acid sequences is one of fundamental issues of modern bioinformatics. Existing algorithms for decision this problem (so called multiple alignment procedures) are not based on any formal problem definition and any model of evolution of proteins. In this paper we propose a new approach for measuring group similarity of proteins, which is founded on probabilistic evolutionary model of transformation of amino acid sequences.
