Phosphoenolpyruvate carboxylase 2
WebPhosphoenolpyruvate carboxylase (PPC; EC 4.1.1.31) catalyzes primary nocturnal CO2fixation in Crassulacean acid metabolism (CAM) species. CAM PPC is regulated posttranslationally by a circadian clock-controlled protein kinase called phosphoenolpyruvate carboxylase kinase (PPCK). WebWith untransformed rice cv. Kitaake as control, the characteristics of carbon assimilation and photoprotection of a transgenic rice line over-expressing maize phosphoenolpyruvate carboxylase (PEPC) were investigated. The PEPC activity in untransformed rice was low, but the activity was stimulated under high irradiance or photoinhibitory condition. PEPC in …

WebPhosphoenolpyruvate carboxylase (PEPC) and its dedicated kinase (PEPC-k) are ubiquitous plant proteins implicated in many physiological processes. This work investigates specific … WebPhosphoenolpyruvate carboxylase (PEPC) is a ubiquitous cytosolic enzyme, which is crucial for plant carbon metabolism. PEPC participates in photosynthesis by catalyzing the initial fixation of atmospheric CO 2 and is abundant in both C 4 and crassulacean acid metabolism leaves. PEPC is differentially expressed at different stages of plant ...
WebC 4 Biochemistry. C 4 photosynthesis begins with the carboxylation of the three-carbon compound phosphoenolpyruvate (PEP) by PEP carboxylase, a cytosolic enzyme that is highly expressed in the M tissue of C 4 plants ( Figure 2 ). PEP carboxylation is the only biochemical step common to all C 4 plants. The product of PEP carboxylation is the ...
