Coronavirus SARS-CoV-2 (responsible for COVID-19) has a spike protein on its surface, which enables it to infect host cells. Initially, proteases in the lungs clip the homo-trimeric spike protein at a unique sequence. This primes it, causing it to extend its receptor binding surface (shown in the above animation), optimizing binding to the host cell's ACE2 receptor (not shown). Next, spike protein initiates fusion of the virus and host cell membranes (not shown), enabling the virus RNA to enter the cell and initiate production of new virions. Knowledge of spike protein's molecular structure and function is crucial to developing effective therapies and vaccines.

In the 1970s, an exciting discovery of a family of medicines was made by the Japanese scientist Satoshi Ōmura. One of these molecules, ivermectin, is shown in this artwork bound in the ligand binding pocket of the Farnesoid X receptor, a protein which helps regulate cholesterol in humans. This structure showed that ivermectin induced transcriptional activity of FXR and could be used to regulate metabolism.

A periplasmic flagellar chaperone protein, FlgA, is required for P-ring assembly in bacterial flagella of taxa such as Salmonella enterica or Escherichia coli. Here we present the open and closed crystal structures of FlgA from Salmonella enterica serovar Typhimurium, grown under different crystallization conditions. An intramolecular disulfide cross-linked form of FlgA caused a dominant negative effect on motility of the wild-type strain.

This tutorial is designed for high school and beginning college students. When we breathe oxygen from the air is taken up by blood in our lungs and soon delivered to each of the cells in our body through our circulatory system. Among other uses, our cells use oxygen as the final electron acceptor in a process called aerobic respiration – a process that converts the energy in food and nutrients into a form of energy that the cell can readily use (molecules of ATP, adenosine triphosphate).
