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.
Application:
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.
