| PHPT1 is a 125aa enzyme belonging to the Janus protein family. Existing as a monomer in the cytoplasm, PHPT1 is an EDTA-insensitive phosphohistidine phosphatase. Overexpression of PHPT1 leads to specific phosphohistidine phosphatase activity towards phosphopeptide I, with no activity detected towards phosphotyrosine, phosphothreonine and phosphoserine peptides. Source: Recombinant protein corresponding to aa1-125 from human PHPT1, fused to His-Tag at N-terminal, expressed in E. coli. Molecular Weight: ~15.9kD (145aa), confirmed by MALDI-TOF Biological Activity: Specific activity is >120units/mg, and is defined as the amount of enzyme that hydrolyze 1nmol f p-nitrophenyl phosphate/minute at pH 7.5 at 37C.
