20627594-2	2010	This provides evidence that covalent inhibitors of POP do not have to be limited to structures containing five-membered N-containing heterocyclic rings.	Nitrogen	120-121	prolyl endopeptidase	Homo sapiens	51-54	
7932578-5	1994	This heterocyclic nitrogen atom would provide a critical hydrogen-bond interaction with the histidine residue of the catalytic triad in PEP.	Nitrogen	18-26	prolyl endopeptidase	Homo sapiens	136-139	
1368673-1	1991	Structural requirements of N-blocked L-proline derivatives as specific inhibitors for prolyl endopeptidase were investigated using a series of substrate analogs.	Nitrogen	27-28	prolyl endopeptidase	Homo sapiens	86-106	
34671446-1	2021	Different five-membered nitrogen-containing heteroaromatics in the position of the typical electrophilic group in prolyl oligopeptidase (PREP) inhibitors were investigated and compared to tetrazole.	Nitrogen	24-32	prolyl endopeptidase	Homo sapiens	114-135
