L-Pyroglutamic acid 2-naphthylamide (CAS 22155-91-5) hydrolyzes selectively in protease-rich environments, releasing free 2-naphthylamine for downstream detection in enzymatic activity assays.
L-Pyroglutamic acid 2-naphthylamide (CAS 22155-91-5) serves as a chromogenic substrate enabling precise detection of pyroglutamate aminopeptidase activity in bacterial isolates. It drives rapid identification of Group A streptococci and enterococci. This selective cleavage generates a visible color change, streamlining differentiation from other streptococcal species in clinical diagnostics.
