The S-layer of the bacterium, a layer of protein found of the surface of cells, has received a significant amount of attention over the past two decades as a potential target to combat the growing threat presented by C. difficile infections. The S-layer contains a wide range of proteins, each of which possess three cell wall binding domains, while many also possess a "functional" region. Here, we present the high resolution structure of the functional region of one such protein, Cwp19 along with preliminary functional characterisation of the predicted glycoside hydrolase. Cwp19 has a TIM barrel fold and appears to possess a high degree of substrate selectivity. The protein also exhibits peptidoglycan hydrolase activity an order of magnitude slower than that of lysozyme and is the first member of glycoside hydrolase-like family 10 to be characterised. This research goes some way to understanding the role of Cwp19 in the S-layer of C. difficile. This article is protected by copyright. All rights reserved.
