title: [The light-induced increase in the activity of NADP(+)-dependent glyceraldehyde-3-phosphate-dehydrogenase : VII. Experiments with ceramium rubrum].
abstract: 1. Tetrasporophytes as well as male and female gemetophytes of Ceramium rubrum show differences in the protein and pigment content, in the activity of the aldolase, and in the light-induced increase in the activity of the NADP(+)-dependent glyceraldehyde-3-phosphate-dehydrogenase (GPD). 2. A very high light intensity is necessary to diminish the increase of the GPD-activity; our Ceramium-material (from shallow water) thus behaves like a strong-light plant. 3. The activity of aldolase in the extract is not influenced by the preceding illumination of the algae. 4. The increase in activity of the NADP(+)-dependent GPD depends on the light quality in a similar way as the intensity of photosynthesis; the phycobilins are also effective as light acceptors in this case. 5. Certain wave-lengths were removed with "minus-filters" from a continuous spectrum (white light). Absence of red-light (663, 714 nm) had no influence on the activation of the enzyme, absence of green light (543, 492) diminished the activating effect, and absence of blue light (463 nm) increased it in comparison to the control (white light).
