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

10 - Combustible liquids

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

In neurons, amyloid β-protein precursor (APP) is transported by binding to kinesin-1, mediated by JNK-interacting protein 1b (JIP1b), which generates the enhanced fast velocity (EFV) and efficient high frequency (EHF) of APP anterograde transport. Previously, we showed that EFV requires

Protein complexes have largely been studied by immunoaffinity purification and (mass spectrometric) analysis. Although this approach has been widely and successfully used it is limited because it has difficulties reliably discriminating true from false protein complex components, identifying post-translational modifications
