4,6-dimethoxy-1,3,5-triazine oligoxyloglucans: novel one-step preparable substrates for studying action of endo-beta-1,4-glucanase III from Trichoderma reesei.
Two kinds of 4,6-dimethoxy-1,3,5-triazine (DMT) oligoxyloglucans, DMT-beta-XXXG and DMT-beta-XLLG, have been synthesized via one-step procedure starting from the corresponding unprotected oligoxyloglucans in water. The resulting DMT derivatives were found to be hydrolyzed by endo-beta-1,4-D-glucanase III from Trichoderma reesei (EGIII) and utilized as substrates for determination of the kinetic parameters of EGIII. The present DMT-method would be a convenient analytical tool for studying the action of glycosyl hydrolases due to the extremely simple synthetic process of DMT-glycosides without using protecting groups.
