Phosphorylated PEPCase is catalytically more active and less sensitive to inhibition by malate than the nonphosphorylated form. PEPCase‐kinase catalyzes the phosphorylation of PEPCase

PPDK-RP make PPDK active removing phosphates of catalytic his/threo residues using ADP as phosphoryl donor, rather than ATP, and the phosphorolytic dephosphorylation of the (PPDK)−Thr−O−P with formation of pyrophosphate, rather than the hydrolysis employed by most protein

phosphatases.

Crassulacean acid metabolism (CAM). Temporal separation of CO2 uptake from photosynthetic reactions: CO2 uptake and fixation take place at night, and decarboxylation and refixation of the internally released CO2 occur during the day. The adaptive advantage of CAM is the reduction of water loss by transpiration, achieved by the stomatal opening during the night.
