Viral Mutations

Viral Mutations

A mutation is a change in the sequence of bases of DNA or RNA in a genome. Some mutations occur during replication of the genome due to errors made by the polymerase enzymes that replicate DNA or RNA. Unlike DNA polymerase, RNA polymerase is prone to errors because it is not capable of “proofreading” its work. Viruses with RNA-based genomes, like HIV, therefore accrue mutations faster than viruses with DNA-based genomes. Because mutation and recombination provide the raw material...

Single Nucleotide Polymorphisms-SNPs

Single Nucleotide Polymorphisms-SNPs

A single nucleotide polymorphism or SNP is a single nucleotide variation at a specific genomic position in a large population. It is the most prevalent type of sequence variation found in the human genome. Point mutations that occur in more than 1% of the population qualify as SNPs. These are present once every 1000 nucleotides on an average in the human genome. Replacement of a purine with another purine (A/G) or a pyrimidine with another pyrimidine (C/T) is known as a transition. In contrast,...

Viruses with RNA Genomes

Viruses with RNA Genomes

RNA viruses are categorized into positive-strand, negative-strand, or double-stranded groups based on their genomic structure and replication mechanisms. This classification dictates how they exploit host cellular machinery for protein synthesis and replication. Some RNA viruses also utilize reverse transcription as part of their life cycle, further diversifying their replication strategies.Positive-Strand RNA VirusesPositive-strand RNA viruses have genomes that function directly as messenger...

Conjugated Proteins

Conjugated Proteins

Simple proteins and protein complexes contain only amino acids. In contrast, many other proteins, called conjugated proteins, covalently bond with non-protein moieties.
Nucleoproteins are protein complexes that contain nucleic acids, categorized as deoxyribonucleoproteins (DNPs) or ribonucleoproteins (RNPs) respectively. The nucleosome is a typical example of a DNP where nuclear DNA is associated with histone proteins. The major antigen for the Covid-19 virus SARS-CoV is an RNP that is critical...

Targets for Drug Action: Overview

Targets for Drug Action: Overview

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...

Background:

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) rapidly spread globally, causing the COVID-19 pandemic.
No specific antiviral drugs or antibodies were available for severe respiratory diseases like COVID-19.
Key viral proteins—spike (S) protein, main protease (Mpro), and RNA-dependent RNA polymerase (RdRp)—are crucial for SARS-CoV-2 invasion and replication, making them prime therapeutic targets.

Purpose of the Study:

To conduct an evolutionary analysis of SARS-CoV-2 compared to other coronaviruses.
To describe the pathogenic mechanisms of SARS-CoV-2.
To review structural details of therapeutic targets and summarize effective inhibitors for COVID-19 treatment.

Main Methods:

Evolutionary analysis of SARS-CoV-2 and related coronaviruses.
Detailed structural analysis of S protein, Mpro, and RdRp.
Examination of complex structures with inhibitors and antibodies.
Comparative analysis of ancestral and D614G mutant S proteins.

Main Results:

Identified S protein, Mpro, and RdRp as critical targets for COVID-19 therapeutics.
Demonstrated that certain neutralizing antibodies and small molecule inhibitors can effectively inhibit these viral targets.
Highlighted structural differences between ancestral and D614G mutant S proteins, linked to increased transmissibility.

Conclusions:

Understanding viral evolution and protein structures is key to developing effective COVID-19 treatments.
A range of chemical molecules and neutralizing antibodies show potential for inhibiting SARS-CoV-2.
Further research into these therapeutic strategies is crucial for combating the pandemic.
