Amino acid substitution matrices from protein blocks. Methods for alignment of protein sequences typically measure similarity by using a substitution matrix with scores for all possible exchanges of one amino acid with another. The most widely used matrices are based on the Dayhoff model of... S...
INTRODUCTION IMGT/DomainGapAlign is the IMGT online tool for the analysis of amino acid (AA) sequences and two-dimensional (2D) structures of domains. The use of this tool is described here. Three domain types can be analyzed: the variable (V) and constant (C) domains of the immunoglobuli...
Pairwise alignment of amino acid sequences is the basic tool of bioinformatics, which is widely used both independently and within numerous more complex methods. The effectiveness of this tool critically depends on the scoring function used, which consists of a substitution matrix and gap penalties....

The primary structure of a protein is the linear sequence of its amino acid (AA) units, starting from the amino-terminal residue (N-terminal) to the carboxyl-terminal residue (C-terminal). From: Emerging Trends in Computational Biology, Bioinformatics, and Systems Biology, 2015 ...
Understanding of amino acid type co-occurrence in trusted multiple sequence alignments is a prerequisite for improved sequence alignment and remote homology detection algorithms. Two objective approaches were used to investigate co-occurrence, both based on variance maximization of the weighted residue frequ...
The latter provides a suitable background amino acid distribution, and should be chosen according to the nature of the query sample, for example, a standard protein database (e.g. SwissProt, PDB), a representative sample of proteins from the organism under study, or a group of proteins with...
Acid from which butyrate ion is derived. Smells of rancid butter, hence the name. butyrolactone autoregulator receptors A group of receptors that bind as homodimers to conserved DNA sequences but are released if the cognate ligand (γ-butyrolactone) binds, thereby allowing gene expression. They ...
-x,--alignment-tool OPTIONAL [muscle]{muscle, clustalw} The system command line tool to be used in a system call to align the amino acid sequences (see -i). The path to the executable can be provided by -y and the command line options can be tweaked using -z. -y, OPTIONAL [...
Therefore, selective PDE4 inhi- bitors have become an important pharmacological tool as novel therapeutics for, for example, the treatment of inflammatory diseases such as asthma, chronic obstructive pulmonary disease or multiple sclerosis.13 Interestingly, we could already show that the amino-acid ...
