Pyrrolidonyl-β-naphthylamide (PYR) is a molecule used in microbiology to detect the presence of pyrrolidonyl peptidase.{{Cite journal | doi = 10.1016/0732-8893(86)90055-6| title = Value of the l-pyrrolidonyl-β-naphthylamide hydrolysis test for identification of select gram-positive cocci| journal = Diagnostic Microbiology and Infectious Disease| volume = 4| pages = 43–47| year = 1986| last1 = Oberhofer| first1 = Thomas R.}} In the presence of bacteria with pyrrolidonyl peptidase, it is broken down to pyroglutamic acid and 2-naphthylamine. To detect this process, p-dimethylaminocinnamaldehyde is added and a change to a pink color can then be detected.
