33992966-6	2021	This electrode showed selectivity for PSA in the presence of bovine serum albumin, glucose and L-cysteine.	Cysteine	95-105	kallikrein related peptidase 3	Homo sapiens	38-41	
24900791-1	2014	Peptide "B-2", which is one of the most potent kallikrein-related peptidase 3 (KLK3)-stimulating compounds, consists of 12 amino acids and is cyclized by a disulfide bridge between the N- and C-terminal cysteines.	Cysteine	203-212	kallikrein related peptidase 3	Homo sapiens	79-83	
27049934-4	2016	An efficient SERS nanoprobe has been constructed using gold nanoparticles as SERS substrate, and the TPE-In as the Raman reporter, which conjugated with a specific peptide substrate, Cys-Ser-Lys-Leu-Gln-OH, well-known for the recognition of prostate-specific antigen (PSA).	Cysteine	183-186	kallikrein related peptidase 3	Homo sapiens	241-272	
33225684-3	2020	The PSA peptides, without free carboxyl sites, are attached to the gold surface via the N-terminal cysteine residue.	Cysteine	99-107	kallikrein related peptidase 3	Homo sapiens	4-7	
30775253-7	2019	This unique, and essentially universal, secretion of enzymatically active PSA into the ECF by mCRPCs creates an exploitable therapeutic index for activation of systemically delivered highly lipophilic toxins as "molecular grenades" covalently linked to cysteine-34 of human serum albumin (HSA) via a stable maleimide containing PSA cleavable peptide such that PSA-dependent hydrolysis (i.e., "detonation") releases the grenades restrictively within the ECF of mCRPC.	Cysteine	253-261	kallikrein related peptidase 3	Homo sapiens	74-77	
19159616-7	2009	This indicated that it is the accessabilty of the Cys 191-Cys 220 disulfide near the catalytic serine 195 that decides on the ability of reductants to inactivate the proteolytic activity of PSA.	Cysteine	50-53	kallikrein related peptidase 3	Homo sapiens	190-193	
21853037-10	2011	The inclusion of serum cysteine to a model with PSA and biopsy Gleason grade improved prediction over the clinical variables alone (p<0.001).	Cysteine	23-31	kallikrein related peptidase 3	Homo sapiens	48-51	
19967419-0	2010	Mimetics of the disulfide bridge between the N- and C-terminal cysteines of the KLK3-stimulating peptide B-2.	Cysteine	63-72	kallikrein related peptidase 3	Homo sapiens	80-84	
19159616-7	2009	This indicated that it is the accessabilty of the Cys 191-Cys 220 disulfide near the catalytic serine 195 that decides on the ability of reductants to inactivate the proteolytic activity of PSA.	Cysteine	58-61	kallikrein related peptidase 3	Homo sapiens	190-193	
3691800-4	1987	gamma-Sm also hydrolyzed the -Phe/Glu- of lysozyme and the -Leu/Cys(SO3H)- of insulin B chain.	Cysteine	64-67	kallikrein related peptidase 3	Homo sapiens	0-8	
11747453-8	2001	Cys(344), which corresponds to Met(358), the P(1) site of alpha1-antitrypsin, was the inhibitory site for elastase-like proteases and PSA, while the preceding residue, Phe(343), was the inhibitory site for chymotrypsin-like proteases.	Cysteine	0-3	kallikrein related peptidase 3	Homo sapiens	134-137	
11067810-9	2000	CONCLUSIONS: With site-specific (cysteine tail) covalent attachment of Fab fragments on a microparticle, subattomole amounts of PSA can be detected quantitatively.	Cysteine	33-41	kallikrein related peptidase 3	Homo sapiens	128-131	
11012675-8	2000	A peptide with four cysteines showed the highest affinity for PSA.	Cysteine	20-29	kallikrein related peptidase 3	Homo sapiens	62-65
