General description
Lambda protein phosphatase is a recombinant protein expressed in Escherichia coli. It requires Mn2+ or Ni2+ as activators.
Biochem/physiol Actions
Lambda protein phosphatase has been used to dephosphorylate HeLa cell extracts.
Can be used to release phosphate groups from serine, threonine or tyrosine residues in proteins. Also active on phosphorylated histidine residues.
Unit Definition
One unit will hydrolyze 1 nanomole of p-nitrophenyl phosphate per min at pH 7.5 at 30 deg C.
Storage Class Code

Infection of Escherichia coli with phage lambda gt10 resulted in the appearance of a protein phosphatase with activity towards 32P-labelled casein. Activity reached a maximum near the point of cell lysis and declined thereafter. The phosphatase was stimulated 30-fold by
