Protein

Glucokinase

Gene

glkA

Organism
Aspergillus niger
Status
Reviewed - 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.
