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

Functioni

The enzyme has great affinity for glucose. Mannose, 2-deoxyglucose and glucosamine can serve as substrates.

Catalytic activityi

ATP + D-glucose = ADP + D-glucose 6-phosphate.

pH dependencei

Activity is relatively constant from pH 7.5 to 9.0. Below pH 7.5, activity decreases with pH.

Similar proteinsi

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 one 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.
