Abstract: A method of improving a ribulose-1,5-bisphosphate carboxylase/oxygenase (RuBisCo) to have a higher protein score is disclosed. The method includes the steps of: making a modified RbcL of the RuBisCo, by, on an RbcL unit of the RuBisCo, either substituting Met for Leu, Phe, Val, or Ile or combinations thereof; substituting Lys for Arg, Thr, or His or combinations thereof; or both of these substitutions. The modified RbcL consequently modifies the RuBisCo and is added to a biomass host where it is stable for homologous recombination. Plastid and nucleus integration was observed. Example RbcL sequences are disclosed with the desirable substitutions. The improved RuBisCo can be used as an improved proteinaceous food source for humans and animals.
