Multitasking proteins: Unexpected properties of galectin-3

A new study, published in Biochemistry this week, examines the biomechanics of sugar-seeking proteins. Specifically, it delves into galectin-3's interaction with glycosaminoglycans (GAG) and proteoglycans. Tarun Dam, an associate ...

New insight into enzyme evolution

How enzymes - the biological proteins that act as catalysts and help complex reactions occur - are 'tuned' to work at a particular temperature is described in new research from groups in New Zealand and the UK, including ...

From good to bad with a copper switch

At the molecular level, the difference between Doctor Jekyll and Mr Hyde lies in a metal, copper. In its physiological form, the prion protein (PrPC ) is 'good' and is involved in normal body processes. It can happen, however, ...
