WebHK2. Hexokinase 2 also known as HK2 is an enzyme which in humans is encoded by the HK2 gene on chromosome 2. [5] [6] Hexokinases phosphorylate glucose to produce glucose-6-phosphate (G6P), the first step in most glucose metabolism pathways. This gene encodes hexokinase 2, the predominant form found in skeletal muscle. WebOct 2, 2024 · Glycolysis, which takes place in the cytoplasm, describes the anaerobic conversion of a single molecule of glucose into two molecules of pyruvate. ... at a rate …
WebHexokinase (HK) is a rate‐limiting enzyme that regulates glucose metabolism in a variety of organisms by converting glucose to glucose‐6‐phosphate. 9 Four different hexokinases have previously been identified, including HK1, HK2, HK3, and HK4. 10 hexokinase domain containing protein‐1 (HKDC1) has recently been identified as a fifth ...
