Acid phosphatase ( EC 3.1.3.2 ) are a group of enzymes that catalyze the hydrolysis of ester variety of orthophosphate . Are commonly found in plant cells , and animal . Among the acid phosphatase distinguish several groups of enzymes with diverse substrate specificity and cellular location . Phosphatase showing a high substrate specificity have been relatively well described and their function in metabolic processes is unknown, while the role of non-specific acid phosphatase has not been fully understood.
