20016463-2	2010	Factor I is a circulating serine protease that inhibits complement by degrading C3b and up to now only a few mutations in the CFI gene have been characterized.	Serine	26-32	complement C3	Homo sapiens	80-83	
6968751-3	1980	The porcine C3a octapeptide is 3 times more active than the common pentapeptide, but the human octapeptide (Ala(70)-Ser-His-Leu(73)-Gly-Leu(75)-Ala-Arg(77) is 12 times more active than the pentapeptide.	Serine	116-119	complement C3	Homo sapiens	12-15	
22654878-7	2012	Further noteworthy chemoattractants are isoforms of transforming growth factor (TGF) beta1-3, which are sensitively recognized by TGF-beta serine/threonine type I and II beta receptors, adenosine, C1q, C3a, and C5a components of the complement, 5-hydroxytryptamine, neuroendocrine peptide catestatin, tumor necrosis factor-alpha, and others.	Serine	139-145	complement C3	Homo sapiens	202-205	
7659097-1	1995	Activation of C3 results in the generation of metastable C3b, which has been shown to preferentially react with the hydroxyl groups of carbohydrates and with specific serine and threonine residues in proteins.	Serine	167-173	complement C3	Homo sapiens	57-60	
11447230-6	2001	This region of the CH1 domain is exposed to solvent and contains a cluster of six potential acceptor sites for ester bond formation with C3b (four Ser and two Thr).	Serine	147-150	complement C3	Homo sapiens	137-140	
11447230-12	2001	Thus Ser-132 is the binding site for C3b on the CH1 domain of the heavy chain, in the Fab region of human IgG.	Serine	5-8	complement C3	Homo sapiens	37-40	
8602875-3	1996	Activated C3b primarily forms ester bonds with hydroxyl groups of carbohydrates on complement activating surfaces, but it has also been shown to react with the hydroxyl group of tyrosine and with specific Ser and Thr residues on IgG and on complement protein C4b.	Serine	205-208	complement C3	Homo sapiens	10-13	
7659097-3	1995	The results demonstrated that Tyr reacts with the thioester of metastable C3b and that this reactivity was 11-fold better than that of threonine, 47-fold better than serine and 50-fold better than the reactivity of carbohydrates.	Serine	166-172	complement C3	Homo sapiens	74-77	
1756717-12	1991	Phosphoamino acid analysis of the synthetic peptides indicated that serine 71 of C3a was phosphorylated by LPK-1.	Serine	68-74	complement C3	Homo sapiens	81-84
