1 | The nitric oxide congener nitrite inhibits myeloperoxidase/H2O2/ Cl- -mediated modification of low density lipoprotein. | Nitrites | myeloperoxidase | Homo sapiens |
2 | Recent studies have shown that myeloperoxidase (MPO), an abundant heme protein released by activated leukocytes, can oxidize nitrite (NO(2-)) to a radical species, most likely nitrogen dioxide. | Nitrites | myeloperoxidase | Homo sapiens |

4 | Furthermore, hypochlorous acid (HOCl), the major strong oxidant generated by MPO in the presence of physiological concentrations of chloride ions, can also react with nitrite, forming the reactive intermediate nitryl chloride. | Nitrites | myeloperoxidase | Homo sapiens |
5 | Interestingly, nitrite concentrations as low as 12.5 and 25 microm significantly decreased MPO/H2O2)/Cl- -induced modification of apoB lysine residues, formation of N-chloramines, and increases in the relative electrophoretic mobility of LDL. | Nitrites | myeloperoxidase | Homo sapiens |
6 | Furthermore, experiments using ascorbate (12.5-200 microm) and the tyrosine analogue 4-hydroxyphenylacetic acid (12.5-200 microm), which are both substrates of MPO, indicated that nitrite inhibits MPO-mediated LDL modifications by trapping the enzyme in its inactive compound II form. | Nitrites | myeloperoxidase | Homo sapiens |
