... and cancer treatments, defensins uniquely target specific membrane lipids via mechanisms distinct from other HDPs. Therefore, defensins could be potentially developed as therapeutics with increased selectivity and reduced susceptibility to the resistance mechanisms of tumour cells and infectious pathogens...

Integral, membrane proteins are embedded in this bilayer, where they interact with lipids from their surroundings, whilst peripheral...

How are these different tasks achieved? Recent advances in structural research of membrane proteins...

X-ray crystallography has provided high-resolution structures for PS-I and the purple bacterial reaction centre, and revealed binding sites for a number of lipids, either embedded in the protein interior or attached to the protein surface. These lipids play a variety of roles, including...

Using a range of down-regulated plants, it has become clear that down-regulation of these genes also causes down-regulation of other components of lipid metabolism, at the activity, translational and transcriptional levels. These plants exhibit effects...

Little difference in the label which accumulated in T A G was observed in the presence or absence of oleoyl-CoA (Fig- ure 2). The experiments...
