The rate and extent of light activation of PEPC may be used as another criterion to distinguish C 3 and C 4 plants. Light stimulated phosphoenolypyruvate carboxylase (PEPC) in leaf discs of C4 plants, the activity being three times greater than that in the dark but stimulation of PEPC was limited ab

A pronounced decrease in phosphoenolpyruvate carboxylase (PEPC) activity is observed upon dark/light transition in Sedum praealtum D.C., only when glycerol is included in the extraction medium. If glycerol is omitted, the activity extracted in light is initially low, but soon reaches night levels. T
Phosphoenolpyruvate (PEP) carboxylase extracted from etiolated and greening sugar cane {a Saccharum hybrid) displayed different properties in terms of DEAE-cellulose elution profile and activation by glucose-6-phosphate. During the first 20 hours of greening, no increase in extractable PEP carboxyla
