Protein

4-alpha-glucanotransferase

Gene

malQ

Organism
Clostridium butyricum
Status
Reviewed-Annotation score: Annotation score: 3 out of 5-Experimental evidence at protein leveli

Functioni

Catalyzes a disproportionation reaction in which single or multiple glucose units from oligosaccharides are transferred to the 4-hydroxyl group of acceptor sugars. Glucose, maltose and maltotriose can act as acceptor, whereas of the three only maltotriose can act as donor.

Catalytic activityi

Transfers a segment of a (1->4)-alpha-D-glucan to a new position in an acceptor, which may be glucose or a (1->4)-alpha-D-glucan.

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into Uniref entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
