Summary
MotViz is a new desktop tool that finds conserved sequence motifs in protein structures. It helps analyze protein families and their functions more efficiently than existing methods.
Area of Science:
- Structural bioinformatics
- Computational biology
- Protein sequence analysis
Background:
- Linking similar proteins structurally is crucial for identifying novel protein family members.
- Conserved sequences within proteins aid in understanding and classifying their exact roles.
- Elucidating the precise function of conserved elements requires structural and physicochemical information.
Purpose of the Study:
- To present MotViz, a novel desktop application for searching and analyzing conserved sequence segments within protein 3D structures.
- To enable users to extract, structurally annotate, and analyze the physicochemical properties of sequence motifs.
- To provide graphical visualization of motif conservation values.
Main Methods:
- Developed a desktop application, MotViz, for motif identification and analysis.
- Integrated a database for storing, retrieving, and functional annotation of motifs.
- Evaluated MotViz efficiency using datasets from 9 protein families.
Main Results:
- MotViz successfully extracts and analyzes sequence motifs from protein structures.
- The application provides structural annotations and physicochemical property analysis for motifs.
- MotViz demonstrated higher efficiency compared to other online motif prediction tools in dataset analysis.
- Graphical visualization of motif conservation values is incorporated.
Conclusions:
- MotViz effectively predicts and visualizes sequence motifs in 3D protein structures with high sensitivity.
- The user-friendly interface, optimized graphics, and backend database contribute to efficient processing.
- MotViz facilitates detailed functional annotation studies through its integrated database.

Sequence Networks of Rotating Machines
A Y-connected synchronous generator, grounded through a neutral impedance, is designed to produce balanced internal phase voltages with only positive-sequence components. The generator's sequence networks include a source voltage that is exclusively in the positive-sequence network. The sequence components of line-to-ground voltages at the generator terminals illustrate this configuration.
Zero-sequence current induces a voltage drop across the generator's neutral impedance and other...

Molecular Models
Physical models representing molecular architectures of chemical compounds play essential roles in understanding chemistry. The use of molecular models makes it easier to visualize the structures and shapes of atoms and molecules.
Multi-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...

Genome Annotation and Assembly
The genome refers to all of the genetic material in an organism. It can range from a few million base pairs in microbial cells to several billion base pairs in many eukaryotic organisms. Genome assembly refers to the process of taking the DNA sequencing data and putting it all back together in a correct order to create a close representation of the original genome. This is followed by the identification of functional elements on the newly assembled genome, a process called genome annotation.
Structural Protein Function
Structural proteins are a category of proteins responsible for functions ranging from cell shape and movement to providing support to major structures such as bones, cartilage, hair, and muscles. This group includes proteins such as collagen, actin, myosin, and keratin.
Collagen, the most abundant protein in mammals, is found throughout the body. In connective tissue, such as skin, ligaments, and tendons, it provides tensile strength and elasticity. In bones and teeth, it mineralizes to form...
