Function[TREA_ECOLI] Provides the cells with the ability to utilize trehalose at high osmolarity by splitting it into glucose molecules that can subsequently be taken up by the phosphotransferase-mediated uptake system.[HAMAP-Rule:MF_01060] Evolutionary Conservation Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf. Publication Abstract from PubMedTotal synthesis of naturally occurring casuarine (1) and the first total synthesis of casuarine 6-O-alpha-glucoside (2) were achieved through complete stereoselective nitrone cycloaddition, Tamao-Fleming oxidation and selective alpha-glucosylation as key steps. Biological assays of the two compounds proved their strong and selective inhibitory properties towards glucoamylase NtMGAM and trehalase Tre37A, respectively, which place them among the most powerful inhibitors of these enzymes. The structural determination of the complexes of NtMGAM with 1 and of Tre37A with 2 revealed interesting similarities in the catalytic sites of these two enzymes which belong to different families and clans.
