Bacterial enzymes may help form plastic substitutes

Biodegradable polymers can now be made using bacterial enzymes according to a study at Science Center of the American Chemical Society (ACS).

One of the The most abundant biopolymers on earth are polysaccharides (sugar chains) could eventually replace some plastics with their flexible and eco-friendly properties.

‘Scientists have identified a previously unknown bacterial enzyme that can generate a new biodegradable molecule (polysaccharide), which could be useful for drug delivery, tissue engineering and other applications. other biomedical applications. ‘

Newly found polysaccharide is similar to biological chitin. The team used genomic data and activity-based screening, to identify a bacterial glycoside phosphorylase enzyme called Acholeplasma laylawii (common contaminant of cell culture in the laboratory).

The team went on to express and purify the new enzyme, which they named . acholetin. The new enzyme has broad potential as a new type of Biocompatible, biodegradable materials.
