Summary
This study introduces a semi-automatic multiple sequence alignment method. It incorporates biological expert knowledge to create more accurate alignments reflecting true biological relationships.
Area of Science:
- Bioinformatics
- Computational Biology
- Genomics
Background:
- Automated multiple sequence alignment methods rely on fixed mathematical rules.
- These methods can fail to produce biologically meaningful alignments due to inherent limitations.
Purpose of the Study:
- To develop a semi-automatic multiple sequence alignment approach.
- To integrate biological expert knowledge into the alignment process for improved accuracy.
Main Methods:
- A software program allows users to define biologically related sites as anchor points.
- The alignment procedure is guided by these user-defined constraints.
Main Results:
- The semi-automatic method produces alignments that respect user-defined biological constraints.
- Alignments generated using biological anchor points more accurately reflect biological relationships.
Conclusions:
- Semi-automatic multiple sequence alignment incorporating expert knowledge enhances biological accuracy.
- This approach offers a more biologically relevant alternative to fully automated methods.

01:49Conserved Binding Sites
Many proteins’ biological role depends on their interactions with their ligands, small molecules that bind to specific locations on the protein known as ligand-binding sites. Ligand-binding sites are often conserved among homologous proteins as these sites are critical for protein function.
Binding sites are often located in large pockets, and if their location on a protein’s surface is unknown, it can be predicted using various approaches. The energetic method computationally analyses the...

00:49Ligand Binding and Linkage
Allosteric proteins have more than one ligand binding site; the binding of a ligand to any of these sites influences the binding of ligands to the other sites. When a protein is allosteric, its binding sites are called coupled or linked. In the case of enzymes, the site that binds to the substrate is known as the active site and the other site is known as the regulatory site. When a ligand binds to the regulatory site, this leads to conformational changes in the protein that can influence the...
02:02Cis-regulatory Sequences
Cis-regulatory sequences are short fragments of non-coding DNA that are present on the same chromosomes as the genes that they regulate. These fragments serve as binding sites for transcriptional regulators, proteins that are responsible for controlling gene transcription and differential gene expression across cell types in eukaryotes. Cis-regulatory sequences can be close to the gene of interest or thousands of bases away in the DNA sequence; however, those sequences that are further away are...
02:51Multi-species Conserved Sequences
Next-generation sequencing technologies have created large genomic databases of a variety of animals and plants. Ever since the human genome project was completed, scientists studied the genome of primates, mammals, and other phylogenetically distant living beings. Such large-scale studies have provided new insights into the evolutionary relationship between organisms.
Although the genome of each species varies greatly from each other, a few sequences are highly conserved. Such conserved DNA...
