Native Thermococcus thioreducens Pyroglutamate Aminopeptidase


Cat No.
NATE-1256
Description
Pyroglutamate aminopetidase is an enzyme that digests proteins. 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.
