Watching a protein as it functions

(Phys.org) —When it comes to understanding how proteins perform their amazing cellular feats, it is often the case that the more one knows the less one realizes they know. For decades, biochemists and biophysicists have ...

RNA folding: A little cooperation goes a long way

(Phys.org)—The nucleic acid RNA is an essential part of the critical process by which the cells in our bodies manufacture proteins. But noncoding RNAs also exist whose sequences, while not converted into proteins, play ...

Reversible method of tagging proteins developed

Chemists at UC San Diego have developed a method that for the first time provides scientists the ability to attach chemical probes onto proteins and subsequently remove them in a repeatable cycle.

Biologists learn how plants synthesize their growth hormone auxin

Biologists at the University of California, San Diego have succeeded in unraveling, for the first time, the complete chain of biochemical reactions that controls the synthesis of auxin, the hormone that regulates nearly all ...

Protein plays role in helping plants see light

Plants do not have eyes or legs, yet they are able to "see" and move toward and away from light. This ability, called phototropism, is controlled by a series of molecular-level signals between proteins inside and between ...
