PHPT1 is a member of the Janus protein familyand is 125 amino acid long. PHPT1 appears as a monomer in the cytoplasm and is an EDTA-insensitive phosphohistidine phosphatase. Overexpression of PHPT1 resolts in specific phosphohistidine phosphatase activity towards phosphopeptide I, with no activity detected towards phosphotyrosine, phosphothreonine and phosphoserine peptides.
Specific activity is >120 units/mg, and is defined as the amount of enzyme that hydrolyze 1nmol f p-nitrophenyl phosphate per minute at pH7.5 at 37°C.
