Other claims from this paper (8)
- Observation PPi-PFK activity is detectable in extracts of a wide variety of primitive and advanced plants.
- Association Angiosperms with extractable PPi-PFK activities 4- to 70-fold higher than ATP-PFK activities tend to be succulent and CAM.
- Intervention effect PPi-PFK activity is not detected in crude extracts of some well-known CAM plants but is revealed by gel filtration or by adding fructose 2,6-bisphosphate.
- Intervention effect Fructose 2,6-bisphosphate activates PPi-PFK activities in extracts of C(3) and C(4) plants.
- Association In C(3) and C(4) plants, PPi-PFK activities are roughly equivalent to ATP-PFK activities in the same species.
- Observation PPi-PFK activity is also detected in some bryophytes, lower vascular plants, ferns and gymnosperms.
- Association Charophytes exhibit at least 4-fold higher PPi-PFK than ATP-PFK activities.
- Mechanism PPi-PFK may serve as an alternate enzyme to ATP-PFK in glycolysis across photosynthetic organisms.
