 (fŏs′fə-tās′, -tāz′)
Any of numerous enzymes that catalyze the removal of phosphate groups by hydrolysis of phosphate ester bonds. They act in the opposite manner to kinases and are important in metabolism and cell signaling.


(ˈfɒsfəˌteɪs; -ˌteɪz)
(Biochemistry) any of a group of enzymes that catalyse the hydrolysis of organic phosphates


(ˈfɒs fəˌteɪs, -ˌteɪz)

any of several classes of esterases of varying specificity that catalyze the hydrolysis of phosphoric esters.
