University of Queensland scientists have found sunflower proteins and their processing machinery are hijacked to make rogue protein rings in a discovery that could open the door to cheaper, plant-based drug manufacturing.
The theory of evolution suggests that present-day organisms evolved from earlier life forms.
(PhysOrg.com) -- Biologists have shown that independent but similar molecular changes turned a harmless digestive enzyme into a toxin in two unrelated species -- a shrew and a lizard -- giving each a venomous bite.
Scientists have discovered an extraordinary protein-cutting enzyme that has also evolved to glue proteins together, a finding that may be valuable in the production of therapeutic drugs.
The iron-sulfur protein IspH plays a central role in the terpene metabolism of several pathogens. The mechanism of the reaction provides an approach for developing new antibiotics, particularly against malaria and tuberculosis. ...
(Phys.org) -- UCLA biochemists have mapped the structure of a key proteinRNA complex that is required for the assembly of telomerase, an enzyme important in both cancer and aging.
Researchers at the University of Dundee have uncovered the mechanism of an important human enzyme that plays a role in the development of debilitating diseases including cancer, dementia and diabetes.
A research group at Umeå University in Sweden has managed to capture and describe a protein structure that, until now, has been impossible to study. The discovery lays the base for developing designed enzymes as catalysts ...
In the past year a group of synthetic proteins called CRISPR-Cas RNA-guided nucleases (RGNs) have generated great excitement in the scientific community as gene-editing tools. Exploiting a method that some bacteria use to ...
With an eye toward understanding DNA replication, Cornell researchers have learned how a helicase enzyme works to actually unzip the two strands of DNA.
