Strings of sugars called polysaccharides are the most abundant biopolymers on Earth. Because of their versatile and environmentally friendly properties, these molecules could eventually replace some plastics. Now, researchers reporting in ACS Central Science have identified a previously unknown bacterial enzyme that can make a new type of polysaccharide, which is similar to the biopolymer chitin. The new molecule is biodegradable and could be useful for drug delivery, tissue engineering and other biomedical applications.

Polysaccharides play many roles in organisms, and because they are biocompatible and biodegradable, these molecules are promising carrier materials for a broad range of therapeutics. The identity of individual sugar molecules in the chain, and the way they are linked together, make them function in different ways. Enzymes known as glycoside phosphorylases can cut certainapart or make new ones, depending on the reaction conditions.

Researchers identify bacterial protein that senses and rescues 'stalled' ribosomesAs a molecular machine found in the cells of all organisms, the ribosome is responsible for making new proteins. It reads the blueprint for a certain protein on a messenger molecule—known as messenger RNA (mRNA)—and then converts this information into new proteins. For a number of reasons, this process can fail, leaving the ribosome stalled on the mRNA and bringing synthesis of the protein to a halt. An international research team led by scientists from the Center for Molecular Biology of Heidelberg University (ZMBH) has now identified a bacterial protein called MutS2 that senses and rescues these stuck protein factories. The fact that the next ribosome on the mRNA chain collides with the stalled ribosome plays a key role.
