Protein

Oligo-1,6-glucosidase IMA4

Gene
IMA4, FSP2, YJL221C, HRE589, J0218
Organism
Saccharomyces cerevisiae (strain ATCC 204508 / S288c) (Baker's yeast)
Status
Reviewed - Annotation score: 4 out of 5 - Protein inferred from homologyi

Functioni

Alpha-glucosidase with broad substrate specificity for alpha-1,4- and alpha-1,6-glucosides. Not required for isomaltose utilization, but overexpression allows the IMA1 null mutant to grow on isomaltose.1 Publication

Catalytic activityi

Hydrolysis of (1->6)-alpha-D-glucosidic linkages in some oligosaccharides produced from starch and glycogen by alpha-amylase, and in isomaltose.
