== Function ==
 +
[https://www.uniprot.org/uniprot/MGA_HUMAN MGA_HUMAN] May serve as an alternate pathway for starch digestion when luminal alpha-amylase activity is reduced because of immaturity or malnutrition. May play a unique role in the digestion of malted dietary oligosaccharides used in food manufacturing.

== Publication Abstract from PubMed ==
 +
Total 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.
