text: # Phosphoric monoester hydrolases
  
  Phosphoric monoester hydrolases (or phosphomonoesterases) are enzymes that catalyse the hydrolysis of O-P bonds by nucleophilic attack of phosphorus by cysteine residues or coordinated metal ions.
  
  They are categorized with the EC number 3.1.3.
  
  Examples include:
  
  * acid phosphatase
  * alkaline phosphatase
  * fructose-bisphosphatase
  * glucose-6-phosphatase
  * phosphofructokinase-2
  * phosphoprotein phosphatase
  * calcineurin
  * 6-phytase
