[[http://www.uniprot.org/uniprot/APHA_SALTY APHA_SALTY]] Dephosphorylates several organic phosphate monoesters such as 3'-UMP, 5'-UMP and pNPP. Also has a phosphotransferase activity catalyzing the transfer of low-energy phosphate groups from organic phosphate monoesters to free hydroxyl groups of various organic compounds such as the 2'-, 3-, or 5'-hydroxyls of nucleosides and nucleotides. Also displays significant phosphomutase activity since it is able to catalyze the transfer of the phosphate group of 3'-AMP from the 3'-position both to the 2'- and 5'-positions. One of the physiological functions of the phosphohydrolytic activity of the enzyme is believed to be the scavenging of organic phosphate esters that otherwise cannot pass the cytoplasmic membrane.<ref>PMID:6256351</ref> <ref>PMID:3049613</ref>
