Protein Sciences uses recombinant DNA technology to produce its vaccines using a single protein from the virus.

With a few exceptions, each gene is responsible for storing the information needed to make a single protein.
The drug worked on the single protein that went defective in GIST cancer cells, and the cancer stabilized.
Something that is beyond the reach of current computers would be to look at folding trajectories for a single protein.
Both firms are basically in the business of finding proteins to treat disease--the modus operandi of the traditional biotechnology company--and get most of their sales from a single protein medicine.
And we have absolutely no way to calculate in principle all the possible interactions and functions of a single protein with the tens of thousands of other proteins in the cell!

Instead of looking at a single gene or protein in isolation, researchers may one day study all of them at once to understand how the body functions and how things go wrong, charting for the first time the intricate biochemical chain reactions that lead to heart disease, diabetes or schizophrenia--and gaining astonishing insights into cures.
Just a few years ago researchers had naively hoped that they could design a drug to blast a single cancer-causing protein and send the disease into remission for years without forcing the patient to endure the side effects of prolonged toxic chemotherapy.
Scientists have for the first time created laser light using living biological material: a single human cell and some jellyfish protein.
Like other viruses, HIV is a stripped-down invader: To reproduce and bud it uses a single, Swiss Army knife of a protein called GAG that hooks onto a protein normally present in healthy cells.
The databases can--in a single day--test one disease-causing protein against a trillion chemical compounds and rank which ones are most likely to latch onto the protein and gum up its works.
Since 1 calorie of beef requires 8 times as much input of grain as a single calorie of bread, Petrela recognizes that rising protein consumption means a rising demand for grains which in turn means a rising demand for global farmland.

The message itself is copied into a single-stranded messenger molecule which carries it to the protein-making parts of the cell, where it is translated.
Tsien's version of the protein produces all of its light when hit by a single color.
