Protein sequence alignment is a key component of most bioinformatics pipelines to study the structures and functions of proteins. Aligning highly divergent sequences remains, however, a difficult task that current algorithms often fail to perform accurat
For this work, we considered 15 Pfam families, and for each we constructed (or retrieved, see below) one MSA from its seed alignment—henceforth referred to as the “seed MSA”—and one from its full alignment—henceforth referred to as the full MSA. The seed MSAs were created by first ...
We propose a Bayesian method to align proteins usingboth the sequence and 3-D structure of the proteins. The problem involves whatare known as "gaps" in the sequence, which we incorporate in our model, and anMCMC implementation is provided. Also, we show that the procedure can be usedto ...

There are almost as many approaches toprotein classificationas there are researchers in the field. The first project driving bioinformatics was the collection ofprotein sequencesso they could be aligned and compared. Working with comparison tools like Fasta and BLAST, and alignment tools like Clustal ...
Multiple Sequence Alignment of NP_666582.1/SIRV2 gp48 and Its Homologs, Related to Figure 6 Homologs were identified by PSI-BLAST as described in STAR Methods. Conserved residues are highlighted black and the eight histidines in gp48 are labeled in red. The phylogenetic tree of AcrIIIB1 ...

Exploiting sequence–structure–function relationships in biotechnology requires improved methods for aligning proteins that have low sequence similarity to previously annotated proteins. We develop two deep learning methods to address this gap, TM-Vec a
For this purpose, multiple sequence alignment (MSA) of the query target sequence is constructed by PSI-BLAST (Altschul et al., 1997) through the NCBI nonredundant (NR) sequence database. Conserved residues in query sequence are then identified from the MSA based on their Jensen-Shannon ...
At each branchpoint of the tree, a structure-based sequence alignment and coordinate transformations are output, with the multiple alignment of all structures output at the root. The algorithm encoded in STAMP (STructural Alignment of Multiple Proteins) is shown to give alignments in good agreement...
