An entropy based heuristic model for predicting functional sub-type divisions of protein families [PDF]

open access: yes, 2009
Multiple sequence alignments of protein families are often used for locating residues that are widely apart in the sequence, which are considered as influential for determining functional specificity of proteins towards various substrates, ligands, DNA ...

Formatt: Correcting protein multiple structural alignments by incorporating sequence alignment

open access: yesBMC Bioinformatics, 2012
Background The quality of multiple protein structure alignments are usually computed and assessed based on geometric functions of the coordinates of the backbone atoms from the protein chains.

A Linear Time Quantum Algorithm for Pairwise Sequence Alignment [PDF]

open access: yesarXiv, 2023
Sequence Alignment is the process of aligning biological sequences in order to identify similarities between multiple sequences. In this paper, a Quantum Algorithm for finding the optimal alignment between DNA sequences has been demonstrated which works by mapping the sequence alignment problem into a path-searching problem through a 2D graph.

Process-oriented Iterative Multiple Alignment for Medical Process Mining

open access: yes, 2017
Adapted from biological sequence alignment, trace alignment is a process mining technique used to visualize and analyze workflow data. Any analysis done with this method, however, is affected by the alignment quality.

An Alternative Model of Amino Acid Replacement [PDF]

open access: yes, 2004
The observed correlations between pairs of homologous protein sequences are typically explained in terms of a Markovian dynamic of amino acid substitution.

Application of Sequence Embedding in Protein Sequence-Based Predictions [PDF]

open access: yesarXiv, 2021
In sequence-based predictions, conventionally an input sequence is represented by a multiple sequence alignment (MSA) or a representation derived from MSA, such as a position-specific scoring matrix. Recently, inspired by the development in natural language processing, several applications of sequence embedding have been observed.

Sequence embedding for fast construction of guide trees for multiple sequence alignment

open access: yesAlgorithms for Molecular Biology, 2010
Background The most widely used multiple sequence alignment methods require sequences to be clustered as an initial step. Most sequence clustering methods require a full distance matrix to be computed between all pairs of sequences.

The construction and use of log-odds substitution scores for multiple sequence alignment. [PDF]

open access: yesPLoS Computational Biology, 2010
Most pairwise and multiple sequence alignment programs seek alignments with optimal scores. Central to defining such scores is selecting a set of substitution scores for aligned amino acids or nucleotides.

Multiple alignment-free sequence comparison [PDF]

open access: yesBioinformatics, 2013
Abstract Motivation: Recently, a range of new statistics have become available for the alignment-free comparison of two sequences based on k-tuple word content. Here, we extend these statistics to the simultaneous comparison of more than two sequences.
