The present invention relates to a method for producing recombinants intended for use in the complete cell-surface protein gp190/MSP1 from plasmodium, especially plasmodium falciparum, as well as the complete DNA sequence of this protein and the appropriate host organisms suited for expressing said sequence, whereby the protein concerned can be entirely synthesized outside the parasite. Also, the inventive method enables sufficient production of above-mentioned protein and its supply as a vaccine. Finally disclosed is a process for stabilizing genes with high At concentration.
