9890644-10	1999	The former sites may be primarily histidine residues of apolipoprotein B-100 that are oxidized to 2-oxo-histidine in the presence of Cu and AA or DHA, thus explaining, at least in part, the unusual inhibitory effect of vitamin C on Cu-induced LDL oxidation.	2-oxohistidine	98-113	apolipoprotein B	Homo sapiens	56-76
8300566-9	1994	The main product present in the hydrolysate of H2O2-treated Cu,Zn-SOD was 2-oxo-histidine.	2-oxohistidine	74-89	superoxide dismutase [Cu-Zn]	Bos taurus	60-69
8300566-16	1994	Taken together, the present study provided direct evidence that 2-oxo-histidine was generated in the Cu,Zn-SOD exposed to H2O2 and that its generation was selective at histidine 118 of the active site of the enzyme.	2-oxohistidine	64-79	superoxide dismutase [Cu-Zn]	Bos taurus	101-110
8594998-2	1995	Oxidation of the C-2 position of the imidazole ring of histidine converts the residue to 2-oxohistidine, a novel amino acid which may serve as a marker of oxidative modification of proteins (K. Uchida and S. Kawakishi, J. Biol.	2-oxohistidine	89-103	complement C2	Homo sapiens	17-20
8594998-8	1995	Using these techniques, a previously unidentified amino acid which appears during the oxidative inactivation of glutamine synthetase was shown to be 2-oxohistidine.	2-oxohistidine	149-163	glutamate-ammonia ligase	Homo sapiens	112-132
