WebPhosphopyruvate carboxylase is not present in liver extracts from foetal rats, but activity appears immediately after birth and increases rapidly over the first day and then more slowly to reach its maximum at the fourth postnatal day. 4. WebIn maize, the phosphopyruvate carboxylase - malic enzyme couple acts to increase the CO 2 concentration in the bundle sheath cells, site of RuDP carboxylase in C 4 species. Maize RuDP carboxylase is also sensitive to O 2 , so this increased CO 2 concentration in the bundle sheath stimulates photosynthesis and reduces photorespiration. WebA procedure is described for the purification of phosphopyruvate (PEP) carboxylase (EC 4.1.1.31) from extracts of Escherichia coli, strain W.
