Although this proteolysis of vitelloge nin by Ca^<2+> was time-consuming (144hr), Vitellogenin was never cleaved in the presence of EDTA and/or serine proteinase inhibitors such as diisopropyl fluorophosphate and phenylmethanesulfonyl fluoride. Intact Vitellogenin was cleaved rapidly (within 8hr) by re-incubating with the proteolytic one. These results suggest that the contamination of proteinases is not responsible for the proteolytic processing of vitellogenin, but Vitellogenin itself contains latent proteinases.}, pages = {31--38}, title = {カルシウムイオンによるティラピアビテロゲニンの分解}, volume = {44}, year = {} }
