Scientists determine how antibody recognizes key sugars on HIV surface 
HIV is coated in sugars that usually hide the virus from the immune system. Newly published research reveals how one broadly neutralizing HIV antibody actually uses part of the sugary cloak to help bind to the virus.

Enzymatic synthesis of pyrrolysine, the mysterious 22nd amino acid
With few exceptions, all known proteins are built up from only twenty amino acids. 25 years ago scientists discovered a 21st amino acid, selenocysteine and ten years ago a 22nd, the pyrrolysine. However, how the cell produces the unusual building block remained a mystery.

Research cracks puzzle of enzyme critical to food supply
If we could make plant food from nitrogen the way nature does, we'd have a much greener method for manufacturing fertilizer – a process that requires such high temperatures and pressures that it consumes about 1.5 percent of the world's energy.

Team solves a protein complex's molecular structure to explain its role in gene silencing
A cell's genome maintains its integrity by organizing some of its regions into a super-compressed form of DNA called heterochromatin. In the comparatively simple organism fission yeast, a cellular phenomenon known as RNA interference (RNAi) plays an essential role in assembling heterochromatin, which keeps the compressed DNA in an inactive or "silent" state.

Photosynthesis is one of the most important biological processes. However, it is less efficient in plants than it could be. Red algae, in contrast, use a slightly different mechanism and are thus more productive. Scientists from the Max Planck Institute of Biochemistry (MPIB) in Martinsried near Munich, Germany, have now identified a so far unknown helper protein for photosynthesis in red algae.

So many proteins, so much promise
The human genome has been mapped. Now, it's on to proteins, a much more daunting task. There are 20,300 genes, but there are millions of distinct protein molecules in our bodies. Many of these hold keys to understanding disease and targeting treatment.

All-access genome: New study explores packaging of DNA
While efforts to unlock the subtleties of DNA have produced remarkable insights into the code of life, researchers still grapple with fundamental questions. For example, the underlying mechanisms by which human genes are turned on and off—generating essential proteins, determining our physical traits, and sometimes causing disease—remain poorly understood.

In biologically active enzyme substrate compounds, as can be found in medicines, water plays a more decisive role than has been imagined up to now. The surrounding water acts like an "adhesive", in order to keep the substrate at the right place on an enzyme. For this, the dynamism of the water is retarded.

Lack of protein FKBP51 in old mice improves resilience to depressive behavior
Decreasing expression of a protein associated with susceptibility to depression made old mice resistant to depressive-like behavior while improving their hormonal response to stress, a study led by researchers at the University of South Florida found. The lack of this protein, FKBP51, did not adversely affect their memory, learning, or basic motor functions.
