Structural highlights

Function

[MALX3_YEAST] Major isomaltase (alpha-1,6-glucosidase) required for isomaltose utilization. Preferentially hydrolyzes isomaltose, palatinose, and methyl-alpha-glucoside, with little activity towards isomaltotriose or longer oligosaccharides. Does not hydrolyze maltose.^{[1] [2]}
