MATCH-UP/MATRIX: a microcomputer program designed to search for protein primary structure homology
1Department of Biological Chemistry, Milton S. Hershey Medical Center, Pennsylvania State University, Hershey 17033.
Summary
The MATCH-UP/MATRIX program aids protein structure determination by comparing amino acid sequences for homology. It identifies significant similarities and detects insertions or deletions between protein structures.
Area of Science:
- Biochemistry
- Computational Biology
- Bioinformatics
Background:
- Determining primary protein structure is crucial for understanding biological function.
- Comparing novel peptide sequences with known proteins aids in structural and functional inference.
- Existing computational tools may lack specific functionalities for homology detection and alignment analysis.
Purpose of the Study:
- To introduce MATCH-UP/MATRIX, a software program for analyzing protein sequences.
- To provide researchers with a tool for identifying amino acid sequence homology.
- To facilitate the detection of insertions and deletions in protein structures.
Main Methods:
- The MATCH-UP/MATRIX program is implemented in Applesoft BASIC for the Apple IIe.
- MATCH-UP compares user-defined peptide sequences against a database of known protein structures.
- MATRIX analyzes and aligns two protein sequences to identify structural variations.
Main Results:
- MATCH-UP identifies peptide-to-protein alignments meeting user-specified homology thresholds.
- MATRIX detects insertions and/or deletions between aligned protein or peptide sequences.
- The program provides a quantitative measure of sequence homology.
Conclusions:
- MATCH-UP/MATRIX offers a valuable computational approach for primary protein structure analysis.
- The software assists in identifying homologous proteins and characterizing sequence variations.
- This tool supports researchers in structural biology and comparative genomics.

Protein Organization
Overview
Protein Families
Protein families are groups of homologous proteins; that is, they have similarities in amino acid sequences and three-dimensional structures. Protein families usually occur because of gene duplication, where an additional copy of a gene is inserted into the genome of an organism. Mutations that change the amino acids but still allow the protein to be properly synthesized, will lead to new protein family members. If these new proteins contain similar amino acids in key locations, protein...
Protein-protein Interfaces
Many proteins form complexes to carry out their functions, making protein-protein interactions (PPIs) essential for an organism's survival. Most PPIs are stabilized by numerous weak noncovalent chemical forces. The physical shape of the interfaces determines the way two proteins interact. Many globular proteins have closely-matching shapes on their surfaces, which form a large number of weak bonds. Additionally, many PPIs occur between two helices or between a surface cleft and a polypeptide...
Protein Networks
An organism can have thousands of different proteins, and these proteins must cooperate to ensure the health of an organism. Proteins bind to other proteins and form complexes to carry out their functions. Many proteins interact with multiple other proteins creating a complex network of protein interactions.
These interactions can be represented through maps depicting protein-protein interaction networks, represented as nodes and edges. Nodes are circles that are representative of a protein,...

Protein Organization
Proteins are polymers of amino acid residues. They are versatile and responsible for different cellular functions, including DNA replication, molecular transport, catalysis, and structural support. Proteins have a hierarchical structure comprising at least three levels of organization: primary, secondary, and tertiary structure. Some large proteins have a quaternary structure where individual protein subunits are linked together.
The primary structure of a protein is its amino acid sequence.
The primary structure of a protein is its amino acid sequence.
Proteomics
A proteome is the entire set of proteins that a cell type produces. We can study proteomes using the knowledge of genomes because genes code for mRNAs, and the mRNAs encode proteins. Although mRNA analysis is a step in the right direction, not all mRNAs are translated into proteins.
Proteomics is the study of proteomes' function. It involves the large-scale systematic study of the proteome to denote the protein complement expressed by a genome. Scientist Mark Wilkins coined the term proteomics...
