AUTOMATED METHOD FOR IDENTIFYING RELATED BIOMOLECULAR SEQUENCES

摘要

The invention relates to an automated method for identifying related biomolecular sequences having defined features of interest from databases, the databases comprising at least a first and a second set of sequences, each set being derived from a different type of organism, comprising the steps of: a) establishing from the first set of sequences a non-redundant list of query sequences having the defined features of interest (first family members), using a database search program; b) performing sequence alignments with the first family members in a second set of sequences derived from a second type of organism, using a database search proram and a preset similarity threshold, giving a list of second family members; c) establishing a two dimensional matrix displaying the first and second family members and their respective similarity values resulting from step (b), optionally displaying only those second family members having similarity values exceeding a preset threshold value; d) selecting from the matrix those pairs of first and second family members for which the similarity values are the best among all of the alignments that involve one of the two pair's members (orthologs).
