SPAP is a subclass of alkaline phosphatase (AP); Alkaline phosphatases are non-specific phosphomonoesterases that catalyze the hydrolysis reaction via a phosphoseryl intermediate to produce inorganic phosphate and the corresponding alcohol, optimally at high pH. Alkaline phosphatase exists as a dimer, each monomer binding 2 zinc atoms and one magnesium atom, which are essential for enzymatic activity. Although SPAP is a subclass of alkaline phosphatase, SPAP has many differences from other APs: 1) the catalytic residue is a threonine instead of serine, 2) there is no binding pocket for the third metal ion, and 3) the arginine residue forming bidentate hydrogen bonding is deleted in SPAP. A lysine and an asparagine residue, recruited together for the first time into the active site, bind the substrate phosphoryl group in a manner not observed before in any other AP.

Type I phosphodiesterase / nucleotide pyrophosphatase; This family consists of phosphodiesterases, including human plasma-cell membrane glycoprotein PC-1 / alkaline phosphodiesterase i / nucleotide pyrophosphatase (nppase). These enzymes catalyze the cleavage of phosphodiester and phosphosulfate bonds in NAD, deoxynucleotides and nucleotide sugars. Also in this family is ATX an autotaxin, tumour cell motility-stimulating protein which exhibits type I phosphodiesterases activity. The alignment encompasses the active site. Also present with in this family is 60-kDa Ca2+-ATPase form F. odoratum.

Ectonucleotide pyrophosphatase/phosphodiesterase, also called autotaxin; Ecto-nucleotide pyrophosphatases/phosphodiesterases (ENPPs) hydrolyze 5'-phosphodiester bonds in nucleotides and their derivatives, resulting in the release of 5'-nucleotide monophosphates. ENPPs have multiple physiological roles, including nucleotide recycling, modulation of purinergic receptor signaling, regulation of extracellular pyrophosphate levels, stimulation of cell motility, and possible roles in regulation of insulin receptor (IR) signaling and activity of ecto-kinases. The eukaryotic ENPP family contains at least five members that have different tissue distribution and physiological roles.

alkaline phosphatases and sulfatases; This family includes alkaline phosphatases and sulfatases. Alkaline phosphatases are non-specific phosphomonoesterases that catalyze the hydrolysis reaction via a phosphoseryl intermediate to produce inorganic phosphate and the corresponding alcohol, optimally at high pH. Alkaline phosphatase exists as a dimer, each monomer binding 2 zinc atoms and one magnesium atom, which are essential for enzymatic activity. Sulfatases catalyze the hydrolysis of sulfate esters from wide range of substrates, including steroids, carbohydrates and proteins. Sulfate esters may be formed from various alcohols and amines. The biological roles of sulfatase includes the cycling of sulfur in the environment, in the degradation of sulfated glycosaminoglycans and glycolipids in the lysosome, and in remodeling sulfated glycosaminoglycans in the extracellular space. Both alkaline phosphatase and sulfatase are essential for human metabolism. Deficiency of individual enzyme cause genetic diseases.
