Antibiotic-resistant bacteria have been emerging at an alarming rate.
Human Argonautes (hAgo), are key proteins involved in a process known as RNA interference.
Light of specific wavelengths can be used to boost an enzyme's function by as much as 30 fold, potentially establishing a path to less expensive biofuels, detergents and a host of other products.
Scientists at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory and collaborators at the Karolinska Institute in Sweden have discovered how an enzyme "knows" where to insert a double bond when desaturating plant fatty acids.
Plants are continually exposed to herbivore attack.
Chemists in MÃ¼lheim devise a new way of optimizing enzymes for industrial applications.
Novel therapies could improve potency of existing AIDS treatments, help to combat drug-resistant virus strains.
A harmless digestive enzyme evolved twice into a dangerous toxin in 2 unrelated species.
Scientists at Fox Chase Cancer Center have discovered a unique method of attack that may be used to inhibit signaling enzymes called kinases, which often have a role in sustaining drug-resistant cancerous cells. They have confirmed that IPA-3, a small molecular inhibitor of a kinase called PAK1, targets the enzyme's regulatory domain, mimicking how enzymes are naturally regulated within cells.
In a landmark technical achievement, investigators in the Vanderbilt Center for Structural Biology have used nuclear magnetic resonance (NMR) methods to determine the structure of the largest membrane-spanning protein to date.
