Phospholysine phosphohistidine inorganic pyrophosphate phosphatase

Gene

LHPP

Organism
Homo sapiens (Human)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

Phosphatase that hydrolyzes imidodiphosphate, 3-phosphohistidine and 6-phospholysine. Has broad substrate specificity and can also hydrolyze inorganic diphosphate, but with lower efficiency (By similarity).By similarity

Catalytic activityi

Diphosphate + H2O = 2 phosphate.1 Publication

Cofactori

Mg2+2 PublicationsNote: Binds 1 Mg2+ ion per subunit.2 Publications

pH dependencei

Optimum pH is 7.0 for PNP, and 5.5 for PPi.1 Publication
