II Transferases

• Enzymes catalysing the transfer of a functional group (G) other than hydrogen between substrates
S - G + S' → S' - G + S

Example:

• Phosphorylation of glucose by hexokinase
Glucose + ATP → Glucose – 6- Phosphate + ADP

Enzyme:

• Recommended name: Hexokinase
• Systematic name: ATP: D-hexose, 6- phosphotransferase
• Enzyme commission No: 2.7.1.1
• 2 → Transferase group (major class)
• 7 → Transfer of phosphate group (sub-class)
• 1 → Alcohol group as acceptor of phosphate group (Sub-sub-class)
• 1 → Hexokinase
