Figure 2.

Western-blot analysis of the induction and degradation of mtCA under mixotrophic and phototrophic growth. A, Amount of mtCA in cells adapted to low-CO₂ conditions for 4 or 8 h in the absence (−Ac) or presence (+Ac) of acetate in the growth medium. All lanes contained 0.5 μg of protein. B, Amount of mtCA in low-CO₂-adapted phototrophic cells after transfer to three different growth conditions for 3 d.
