additional information MLG:xyloglucan endotransglucosylase, MXE, catalyses a reaction similar to XET activity, EC 2.4.1.207, which catalyses the endocleavage of xyloglucan as donor substrate and the creation of a glycosidic link between the newly formed potentially reducing terminus and the nonreducing terminus of another xyloglucan or xyloglucan oligosaccharide molecule as acceptor substrate, but uses mixed-linkage (1->3), (1->4)-beta-D-glucan, MLG,s as a donor substrate as opposed to xyloglucan, cleavage specificity, overview Equisetum arvense ?

General Information

General Information Comment Organism
physiological function among land-plant hemicelluloses, xyloglucan is ubiquitous, whereas mixed-linkage (1->3), (1->4)-beta-D-glucan, i.e. MLG, is confined to the Poales and Equisetales. The enzyme MLG:xyloglucan endotransglucosylase, MXE, grafts MLGto xyloglucan. MLG is absent in the most immature cells tested (callus culture) and highly prevalent in older tissues, whereas xyloglucan content is higher in young tissues Equisetum arvense
