Biosynthesis of the 25-kDa protein in the macrogametes/zygotes of Plasmodium falciparum.
Synthesis of the 25-kDa protein in the early midgut stages of Plasmodium falciparum was studied, using metabolic inhibitors (colchicine and actinomycin D) and pulse-labeling experiments. Experiments with colchicine showed that, immediately after induction of macrogametogenesis, 25-kDa protein synthesis occurs in both fertilized and nonfertilized macrogametes. The amount of 25-kDa protein synthesized increased slowly during time. Experiments with actinomycin D revealed that the slow increase of synthesis may be dependent on de novo messenger RNA synthesis.
