Cofactors and Coenzymes01:24

Cofactors and Coenzymes

8.4K
Enzymes are proteins made of amino acids. The functional group of each constituent amino acid catalyzes a wide variety of chemical reactions via ionic interactions or acid-base reactions. However, amino acids cannot catalyze oxidation-reduction and group transfer reactions and need to be aided by non-protein components called cofactors. Cofactors are also referred to as the chemical teeth of an enzyme.
Cofactors can be metallic ions or organic molecules called coenzymes. These types of helper...

Enzymes require additional components for proper function. There are two such classes of molecules: cofactors and coenzymes. Cofactors are metallic ions and coenzymes are non-protein organic molecules. Both of these types of helper molecule can be tightly bound to the enzyme or bound only when the substrate binds.

Targets for Drug Action: Overview

9.2K
Drugs target macromolecules to modify ongoing cellular processes. Primary drug targets include receptors, ion channels, transporters, and enzymes.
Receptors are either membrane-spanning or intracellular proteins, which upon binding a ligand, get activated and transmit the signal downstream to elicit a response. Drugs bind receptors, either mimicking the action of endogenous ligands or blocking the receptor activity to bring about a modified response. Nearly 35% of approved drugs target the G...

Mass Analyzers: Overview

2.0K
The mass analyzer is a crucial component of the mass spectrometer. In the ionization chamber, the vaporized sample is bombarded with a high-energy electron beam to generate a radical cation and further fragment into neutral molecules, radicals, and cations. A series of negatively charged accelerator plates accelerate the cations into the mass analyzer. The mass analyzer separates ions according to their mass-to-charge (m/z) ratios and then directs them to the detector. The common types of mass...

Area of Science:

  • Bioinformatics
  • Molecular Biology
  • Computational Biology

Background:

  • MicroRNAs (miRNAs) regulate gene expression post-transcriptionally by targeting messenger RNAs (mRNAs).
  • A single miRNA can target multiple mRNAs, and a single mRNA can be targeted by multiple miRNAs, leading to complex regulatory networks.
  • Identifying combinatorial miRNA regulation and co-functionally enriched miRNA pairs presents significant analytical challenges.

Purpose of the Study:

  • To develop a user-friendly web tool, C2Analyzer, for analyzing microRNA co-targeting and co-functional enrichment.
  • To facilitate the identification of miRNA pairs regulating shared biological processes.
  • To provide insights into complex post-transcriptional gene regulation.

Main Methods:

  • Development of C2Analyzer, a Perl-based web tool.
  • Utilizing hypergeometric analysis to determine co-functional enrichment of miRNA pairs.
  • Identifying sets of miRNAs targeting specific Gene Ontology (GO) terms.
  • Identifying co-targeting miRNA pairs, their mRNA targets, and associated GO processes.

Main Results:

  • C2Analyzer can determine if given miRNA pairs are co-functionally enriched for specific GO terms.
  • The tool identifies sets of miRNAs whose targets are enriched within specified GO terms.
  • C2Analyzer identifies co-targeting miRNA pairs, their targets, and the GO processes involved, enabling network visualization.

Conclusions:

  • C2Analyzer is a versatile and user-friendly tool for analyzing complex miRNA-miRNA co-functional relationships.
  • The tool aids researchers in understanding combinatorial gene regulation and identifying functionally related miRNA pairs.
  • The output facilitates further network analysis and visualization, advancing the study of post-transcriptional regulation.
