10816562-4	2000	The PC1 inhibitory region of proSAAS was mapped to an 8-12-residue region near the C terminus that includes a critical Lys-Arg sequence.	Lys-Arg	119-126	proprotein convertase subtilisin/kexin type 1	Homo sapiens	4-7	
7768927-6	1995	Both SPC2 and SPC3 participate in the processing of prohormones at dibasic cleavage sites, typically Lys-Arg or Arg-Arg.	Lys-Arg	101-108	proprotein convertase subtilisin/kexin type 1	Homo sapiens	14-18	
1905715-6	1991	By contrast, when the Lys-Arg precursor was coexpressed with the two mammalian proteases in endocrine cells with no endogenous processing activity at dibasic sites, it was cleaved only by PC3.	Lys-Arg	22-29	proprotein convertase subtilisin/kexin type 1	Homo sapiens	188-191	
9756897-7	1998	In PC1, this subsite displayed a strong preference toward occupation by Leu; the Ki value for peptide Ac-Leu-Leu-Arg-Val-Lys-Arg-NH2 was 28 times lower than that for peptide Ac-Ile-Ile-Arg-Val-Lys-Arg-NH2.	Lys-Arg	121-128	proprotein convertase subtilisin/kexin type 1	Homo sapiens	3-6	
1647029-3	1991	Similarly to pituitary corticotrophs, PC3 expressed in processing-deficient BSC-40 cells cleaved native mouse POMC at the -Lys-Arg- sites flanking corticotropin.	Lys-Arg	123-130	proprotein convertase subtilisin/kexin type 1	Homo sapiens	38-41
