1. An enzyme that catalyzes the phosphorylation of glucose to glucose-6-phosphate, playing a key role in glucose metabolism and blood sugar regulation.
Usage: biochemistry; also called hexokinase IV

Examples

• Glucokinase is primarily found in the liver and pancreatic beta cells.
• The enzyme glucokinase acts as a glucose sensor in the body.
• Mutations in the glucokinase gene can lead to maturity-onset diabetes of the young.
• Glucokinase has a higher Km value for glucose compared to other hexokinases.
• Researchers are studying glucokinase activators as potential diabetes treatments.
