RESEARCH: PLASMEPSIN-II
FOLDING PROJECT #17259 PROFILE

This project uses computer models to find hidden pockets in a protein that causes malaria. These pockets could be used to design new drugs to fight the disease.

Note: This TLDR is a simplication and may not be 100% accurate.

Identification of drug binding pockets is crucial for drug discovery research.

Drug binding pockets often remain hidden in the experimentally determined structures.

Protein dynamics can reveal protein confomrations that expose such drug binding pockets in some of the high-energy states that remain unidentified by experimental techniques.

Here, we combine the power of alpha-fold and molecular dynamics simulations to generate an ensemble of protein conformations to find drug binding pockets in plasmepsin-II protein from Plasmodium falciparum that degrades host haemoglobin.

Drug binding pockets

Regions on a protein where drugs can bind.

Drug binding pockets are areas on proteins where medications attach. Understanding these pockets is crucial for developing new drugs because it helps scientists design medications that specifically target and interact with proteins involved in diseases.

Protein dynamics

The motion and flexibility of proteins.

Protein dynamics refers to the constant movement and changes in shape that proteins undergo. This movement is essential for their function, allowing them to interact with other molecules, change shape, and carry out various tasks within cells.

Alpha-fold

An AI system for predicting protein structures.

AlphaFold is a powerful artificial intelligence program developed by DeepMind that can accurately predict the 3D shape of proteins from their amino acid sequence. This breakthrough has revolutionized structural biology and drug discovery.

Molecular dynamics simulations

Computer models that simulate the movement of atoms and molecules.

Molecular dynamics simulations are computer programs that use mathematical equations to model the movement and interactions of atoms and molecules. This allows scientists to study how proteins fold, interact with other molecules, and undergo chemical reactions.

Plasmepsin-II

A protease enzyme found in the malaria parasite.

Plasmepsin-II is an important enzyme produced by the Plasmodium falciparum parasite, which causes malaria. This enzyme helps break down hemoglobin from red blood cells, providing nutrients for the parasite to grow and multiply.

Plasmodium falciparum

The species of malaria parasite that causes the most severe form of the disease.

Plasmodium falciparum is a single-celled parasite responsible for the deadliest type of malaria. It infects red blood cells and can cause severe complications such as organ damage, coma, and death.

Haemoglobin

The protein in red blood cells that carries oxygen.

Haemoglobin is the iron-containing protein found in red blood cells. It has the crucial function of binding to oxygen in the lungs and transporting it throughout the body to deliver oxygen to tissues and organs.
