33111012-2	2020	The system comprised of the FR ligand folic acid (FA), glycine-phenylalanine-leucine-glycine (Gly-Phe-Leu-Gly, GFLG), which can be specifically cleaved by cathepsin B, and the anticancer drug mitomycin C (MMC).	Leucine	77-84	cathepsin B	Homo sapiens	155-166	
3911093-4	1985	Cathepsin B hydrolyzed angiotensin I via a dipeptidyl carboxypeptidase mechanism removing His-Leu to form angiotensin II, and it degraded angiotensin II as an endopeptidase at the Val3-Tyr4 bond.	Leucine	94-97	cathepsin B	Homo sapiens	0-11	
3318115-6	1987	Cathepsin B split off the C-terminal dipeptide in synthetic substrates Leu-Trp-Met-Arg-Phe-Ala and Trp-Met-Arg-Phe-Ala but not in Met-Arg-Phe-Ala.	Leucine	71-74	cathepsin B	Homo sapiens	0-11	
19401154-4	2009	FhcatB1 has biochemical properties distinct from mammalian cathepsin B enzymes, with an atypical preference for Ile over Leu or Arg residues at the P(2) substrate position and an inability to act as an exopeptidase.	Leucine	121-124	cathepsin B	Homo sapiens	59-70	
8931723-4	1996	The analogue in which the D-leucine residue of poststatin was replaced by L-leucine showed strong inhibitory activity to cathepsin B.	Leucine	74-83	cathepsin B	Homo sapiens	121-132	
12213061-8	2002	The Z-Arg-Leu-Val-Agly fragment, covalently linked to Cys29 of cathepsin B, was also developed and modeled, in the catalytic pocket of the enzyme, through a molecular dynamics approach, to analyze ligand-protein interactions in detail.	Leucine	10-13	cathepsin B	Homo sapiens	63-74	
7716141-6	1995	Synthetic human C-peptide was rapidly cleaved by purified human cathepsin B, primarily at the site of leucine residues, to give several metabolites, including the (1-25) and (1-23) fragments.	Leucine	102-109	cathepsin B	Homo sapiens	64-75
