WebNov 5, 2004 · Abstract. Motivation: Protein homology detection and sequence alignment are at the basis of protein structure prediction, function prediction and evolution. Results: We have generalized the alignment of protein sequences with a profile hidden Markov model (HMM) to the case of pairwise alignment of profile HMMs. We present a method … WebHomology means that two sequences have the same evolutionary origin (both have evolved from the same ancestral sequence). If sequences are sufficiently similar you may assume that this is due to ...

WebMay 17, 2011 · The server can be used to search for structural relatives of a query protein ( Figure 1 A) or to compare two protein structures ( Figure 1 B). In both cases, the user can decide whether to carry out alignments for the complete structure (global) or to look for the best local similarity (local). ...

WebSep 20, 2012 · Abstract. The notion that sequence homology implies functional similarity underlies much of computational biology. In the case of protein-protein interactions, an interaction can be inferred between two proteins on the basis that sequence-similar proteins have been observed to interact. The use of transferred interactions is common, … WebMar 25, 2015 · A common approach to identify orthologs (homology between two genes resulting from a speciation event) it 'best bidirectional match': if you blast gene A (in … WebMultiple Sequence Alignment (MSA) is generally the alignment of three or more biological sequences (protein or nucleic acid) of similar length. From the output, homology can be inferred and the evolutionary relationships between the sequences studied. By contrast, Pairwise Sequence Alignment tools are used to identify regions of similarity that may … mayfield labs tiverton
