| Abstract: | Immunotitration of phosphoenolpyruvate carboxylase (EC 4.1.1.31) extracted from leaves of Kalanchoe blossfeldiana v. Poelln. cv. Tom Thumb. It was established that at different times of the day-night cycle the daily rhythm of enzyme capacity does not result from a rhythm in protein synthesis, but rather from changes in the specific activity of the enzyme.Abbreviations CAM Crassulacean acid metabolism - IgG immunoglobulin G - PEP phosphoenolpyruvateTo whom correspondence should be addressed |
