Researchers at the University of Birmingham and Newcastle University have successfully identified and characterised one of the key enzymes involved in this process. They demonstrated how the enzyme enables bacteria to break down and feed off sugars in the layers of mucus lining the gut.
The research offers a significant step forward in our understanding of the complex co-dependent relationships at work in the gut, about which little is currently known. Because the mechanism used by the enzyme is particularly distinctive, the researchers anticipate it can be used in the development of new diagnostics for intestinal diseases.
The molecules in mucus, called mucin, are constantly produced by the body to generate the layer of mucus in the gut that provides a barrier between the gut’s complex populations of bacteria and the rest of the body. Mucin contain chains of sugar molecules called glycans, and these also provide an essential source of nutrients for bacteria.
