Chlorides 0-8 myeloperoxidase Homo sapiens 28-31 9742209-9 1998 Chloride acted as a substrate for MPO and as an activator in MPO-catalysed sulphoxidation. Chlorides 0-8 myeloperoxidase Homo sapiens 34-37 9742209-9 1998 Chloride acted as a substrate for MPO and as an activator in MPO-catalysed sulphoxidation. Chlorides 0-8 myeloperoxidase Homo sapiens 61-64 9742209-11 1998 In the presence of 100 mM chloride the catalytic efficiency (kcat/Km) of MPO increased 3-4-fold, whatever the sulphide considered, but racemic products were obtained. Chlorides 26-34 myeloperoxidase Homo sapiens 73-76
