1 In the current studies, we show that hypochlorous acid (HOCl), generated by the myeloperoxidase-hydrogen peroxide-chloride system of phagocytes, cross-links single-stranded DNA-binding protein (SSB) to single-stranded oligonucleotides. Chlorides myeloperoxidase Homo sapiens
2 The covalent complex of radiolabeled dT(40) and SSB was also generated by chloramines and the complete myeloperoxidase-hydrogen peroxide-chloride system. Chlorides myeloperoxidase Homo sapiens
3 The enzymatic reaction required each component of the system and was inhibited by heme poisons and chloride-free conditions, implicating myeloperoxidase and HOCl. Chlorides myeloperoxidase Homo sapiens
