Evolutionary Relationships through Genome Comparisons

Evolutionary Relationships through Genome Comparisons

Genome comparison is one of the excellent ways to interpret the evolutionary relationships between organisms. The basic principle of genome comparison is that if two species share a common feature, it is likely encoded by the DNA sequence conserved between both species. The advent of genome sequencing technologies in the late 20th century enabled scientists to understand the concept of conservation of domains between species and helped them to deduce evolutionary relationships across diverse...

Background:

Understanding biopolymer molecular function necessitates studying structural characteristics.
Automated structure visualization tools are crucial due to the increasing number of available structures.
Current methods often require manual intervention for structure visualization.

Purpose of the Study:

To present a novel web server and method for automated graphical sequence representation of molecular structures.
To facilitate the understanding of biopolymer structural characteristics through enhanced visualization.
To provide researchers with an efficient tool for analyzing complex molecular structures.

Main Methods:

SequenceCEROSENE (color encoding of residues obtained by spatial neighborhood embedding) method developed.
Retrieves amino acid/nucleotide sequences and color-codes residues based on 3D structure information.
Processes and reports additional heteroatoms and bound chemical compounds (ligands, coenzymes).

Main Results:

Generates color-highlighted sequences representing 3D residue locations.
Enables deduction of spatial interactions, proximity, and relations from color similarity.
Web server provides access to visualizations (Protein Data Bank or uploaded models) and raw data downloads.
Interactive visualizations and 3D structure viewing are supported.

Conclusions:

SequenceCEROSENE aids in quickly perceiving general structural characteristics of biopolymers and complexes.
The web server supports researchers in the initial phase of structure-based studies.
Interactive features and efficient processing of multiple structures make the tool valuable for researchers.
