Peroxide induced chemiluminescence in an in vitro proline hydroxylation system.
This communication describes a hydrogen peroxide (HOOH) induced chemiluminescence (CL) in an in vitro aromatic (proline) hydroxylation system. The reactive components of the system are ascorbic (AA), ethylene diamine tetraacetic disodium salt (EDTA), ferrous sulfate, and HOOH. The CL is (1) nearly dissipated within three minutes, (2) enhanced and/or sustained by proline and polylysine to a greater degree than by alanine, (3) partially inhibited by a,a' dipyridyl, EDTA, and ethanol, (4) most dependent upon the presence of Fe2+, AA, and HOOH. The in vitro proline hydroxylation system is more effective than ground state oxygen in terms of the CL produced and the percent of hydroxyproline formed.
