title: [Protective effect of extracellular protein metabolite of Luteococcus japonicus subsp, casei on cells subjected to heating and UV irradiation].
abstract: Extracellular protein metabolite isolated from the culture liquid of Luteococcus japonicus subsp. casei had reactivating and protective effects on UV-irradiated and heated cells. The extracellular metabolite, produced by cells in the logarithmic growth phase, was present in culture liquid in minuscule amounts. Mass spectral analysis showed that, along with the major component with a molecular weight of 7.6 kDa, the preparation contained low quantities of three minor proteins. Apparently, the biological activity of the exometabolite is determined by the major polypeptide component.
