CC   -!- FUNCTION: Dephosphorylates several organic phosphate monoesters. Also
CC       has a phosphotransferase activity catalyzing the transfer of low-energy
CC       phosphate groups from organic phosphate monoesters to free hydroxyl
CC       groups of various organic compounds (By similarity).
CC       {ECO:0000250|UniProtKB:P0AE22}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=a phosphate monoester + H2O = an alcohol + phosphate;
