How a Glycoside Hydrolase Recognizes a Helical Polyglucan
How a Glycoside Hydrolase Recognizes a Helical Polyglucan.
Abstract
Similarly to other biopolymers, linear polysaccharides can form double- or triple-helical structures. How enzymes recognize and manage this quaternary structure is an unresolved question. In this issue of Structure, Pluvinage et al. (2017) shed light on the structural complementarity between family GH81 glycoside hydrolase and the quaternary structure of their polysaccharide substrates.
