Descrizione generale

Pyroglutamate Aminopeptidase from Pyrococcus furiosus, also called the deblocking aminopeptidase, is a 42 kDa protein and belongs to aminopeptidase A family. It shares sequence homology with aminopeptidase in the active site, with conserved zinc and cobalt binding residues.

Applicazioni

Pyroglutamate Aminopeptidase, from Pyrococcus furiosus is a recombinant, thermostable aminopeptidase that is expressed in Escherichia coli. It is used to cleave pyroglutamic acid which allows analysis of N-terminal sequences of peptides.
The enzyme from Sigma has been used for the removal of pyroglutamate (pGlu) N-terminal blocking group, under reduced conditions, prior to N-terminal sequencing of purified cassiicolin.
Thermostable aminopeptidase that liberates N-terminal pyroglutamic acid from proteins and peptides prior to Edman degradation.

Azioni biochim/fisiol

Pyroglutamate Aminopeptidase (PGP 1) interacts with immunoglobulin, functions as inflammatory cytokine and modulates immune response. The levels PGP 1 is elevated during inflammation.
This enzyme is specific for N-terminal pyroglutamic acids. It cleaves the N-terminal pyroglutamic acid from proteins and peptides prior to Edman degradation. The optimal temperature range is 95 to 100 °C and the optimal pH range is 6.0 to 9.0.

Definizione di unità

One unit will hydrolyze 1 μmol of pyroglutamate p-nitroanilide per minute at pH 7.0 at 37 °C.

Stato fisico

Lyophilized powder containing sodium phosphate

Nota sulla preparazione

Reconstitute the vial of enzyme with 50 μl of 50 mM sodium phosphate, pH 7.0, with 10 mM DTT and 1 mM EDTA. The reconstituted solution should be stored at -20 °C.

Typically, the removal of pyroglutamate from the protein chains of immunoglobulins with the enzyme pyroglutamate aminopeptidase requires the use of chaotropic and reducing agents, quite often with limited success. This article describes a series of optimization experiments using elevated temperatures
