Iterative homology searches

Web6 dec. 2016 · INTRODUCTION. Protein similarity searching is central to interpreting genome sequence data. The widely used BLAST program can routinely identify homologous proteins that diverged >2 billion years ago, and share as little as 20–25% sequence identity.For most large, well-characterized protein families, a single BLAST search … WebA set of known pathways was used as input for an iterative homology search approach. The resulting MGC collection was screened and helped to design the general detection rules. The original Genbank files of this subset of pathways can be downloaded from here: subset_known_pathways.zip

Web1 mei 2015 · PSI-BLAST is an iterative version of BLAST, which takes a single protein sequence query and database as inputs. Its first iteration is the same as a BLAST search. At the end of that iteration and each subsequent one, it performs uniform E-value thresholding on the retrieval list (at a stringent default E-value threshold of 0.002).
