When harmful bacteria or viruses enter the body, immune cells spot telltale proteins known as antigens on the invaders' surfaces and send out armies of antibodies to fend them off. If some of those antibodies have just the ...

How cells 'read' artificial ingredients tossed into genetic recipe

If the genome is the recipe of life, base pairs are the individual ingredients listed. These chemical structures form DNA, and every living organism on Earth has just four. The specific arrangements of these four base pairs—A, ...

A safer way to deploy bacteria as environmental sensors

In recent years, scientists have developed many strains of engineered bacteria that can be used as sensors to detect environmental contaminants such as heavy metals. If deployed in the natural environment, these sensors could ...

Revealing the way a critical enzyme works in the cell

S-acylation is the process of chemically linking a lipid to protein via a thioester bond. It is an important process of the cell that regulates the localization and function of numerous proteins. It promotes lipid membrane ...
