41. Pre-ejaculate contains some chemicals associated with semen, such as acid phosphatase . 42. This enzyme was later renamed liver phosphorylase phosphatase . 43. Some research supports that compounds in the plant inhibit glucose-6-phosphatase . 44. The addition of a phosphoryl group to an enzyme is catalysed by phosphatase enzymes. 45. Insulin stimulates the activity of pyruvate dehydrogenase phosphatase . 46. This modification generates the binding site for the phosphatase , a SH2 recognition domain. 47. Phosphatase enzymes are also used by soil microorganisms to access organically bound phosphate nutrients.48. Cdc25 phosphatase were also suggested as possible substrates. 49. An example amplifier molecule is an oligonucleotide chain bound to the enzyme alkaline phosphatase . 50. This gene encodes the phosphatase 2A catalytic subunit.
