Purity: > 90% by SDS - PAGE Format: Liquid. In 20mM Tris-HCl buffer (pH 8.0) containing 1mM DTT, 10% glycerol, 0.1M NaCl. Phospholysine phosphohistidine inorganic pyrophosphate phosphatase, also known as LHPP, is a member of the HAD-like hydrolase superfamily. It is a unique enzyme that hydrolyzes not only oxygen-phosphorus bonds in inorganic pyrophosphate but also nitrogen-phosphorus bonds in phospholysine, phosphohistidine and imidodiphosphate in vitro. LHPP is expressed in liver, kidney and moderately in brain. Recombinant human LHPP protein, fused to His-tag at N-terminus, was expressed in E.coli and purified by using conventional chromatography techniques.
