phosphohydrolases

phos·pho·hy·dro·las·es

(fos'fō-hī'drō-lās'ĕz),
Phosphoric monoester hydrolases; enzymes (EC 3.1.3.x) cleaving phosphoric acid (as orthophosphate) from its esters; trivial names usually end in phosphate.

S1P can be dephosphorylated back to sphingosine by two specific S1P phosphatases (SPP1 and SPP2), which belong to the family of magnesium-dependent, N-ethylmaleimide-insensitive type 2 lipid phosphate phosphohydrolases that reside in the endoplasmic reticulum [32, 52, 53].

However, organic P forms, particularly phytates, are predominant in most soils (10-50% of total P) and must be mineralized by phytases (myo-inositol hexakisphosphate phosphohydrolases) to be available P for plants [8].
Lipid phosphate phosphohydrolases (LPPs), also known as phosphatidate phosphohydrolase-2 (PAP-2), are the [Mg.sup.2+]-independent and N-ethylmaleimide-insensitive N-glycosylated integral membrane ectophosphohydrolase [1, 2].
The three phosphohydrolases showed uniformly high activities, and there were no consistent rankings among the species or parts of the digestive system.
In order to minimize such problems, microbial phytases are added in broiler diets, because the phytase (myo-inositol hexakisphosphate phosphohydrolases) catalyzes the hydrolysis of phytic acid in a stepwise manner, releasing lower inositol phosphates and inorganic phosphate that can be used metabolically by the poultry (VATS & BANERJEE, 2004).
