Amylo-alpha-1,6-glucosidase. This family includes human glycogen branching enzyme AGL. This enzyme contains a number of distinct catalytic activities. It has been shown for the yeast homolog GDB1 that mutations in this region disrupt the enzymes Amylo-alpha-1,6-glucosidase (EC:3.2.1.33).

glycogen debranching enzyme, archaeal type, putative. The seed for this model is composed of two uncharacterized archaeal proteins from Methanosarcina acetivorans and Sulfolobus solfataricus. Trusted cutoff is set so that essentially only archaeal members hit the model. The notable exceptions to archaeal membership are the Gram positive Clostridium perfringens which scores much better than some other archaea and the Cyanobacterium Nostoc sp. which scores just above the trusted cutoff. Noise cutoff is set to exclude the characterized eukaryotic glycogen debranching enzyme in S. cerevisiae. These cutoffs leave the prokaryotes Porphyromonas gingivalis and Deinococcus radiodurans below trusted but above noise. Multiple alignments including these last two species exhibit sequence divergence which may suggest a subtly different function for these prokaryotic proteins.

Glycogen debranching enzyme (alpha-1,6-glucosidase) [Carbohydrate transport and metabolism].

glycogen debranching enzymye. glycogen debranching enzyme possesses two different catalytic activities; oligo-1,4-->1,4-glucantransferase (EC 2.4.1.25) and amylo-1,6-glucosidase (EC 3.2.1.33). Site directed mutagenesis studies in S. cerevisiae indicate that the transferase and glucosidase activities are independent and located in different regions of the polypeptide chain. Proteins in this model belong to the larger alpha-amylase family. The model covers eukaryotic proteins with a seed composed of human, nematode and yeast sequences. Yeast seed sequence is well characterized. The model is quite rigorous; either query sequence yields large bit score or it fails to hit the model altogether. There doesn't appear to be any middle ground. [Energy metabolism, Biosynthesis and degradation of polysaccharides]

Glycogen debranching enzyme N terminal. This domain family is found in bacteria and archaea, and is typically between 218 and 229 amino acids in length. The family is found in association with pfam06202. Glycogen debranching enzyme catalyzes the debranching of amylopectin in glycogen. This is done by transferring three glucose subunits of glycogen from one parallel chain to another. This has the effect of enabling the glucose residues to become more accessible for glycolysis.
