Synthesizing ammonia
WebMethods are provided for the synthesis and secretion of recombinant hetero-multimeric proteins in mating competent yeast. A first expression vector is transformed into a first haploid cell; and a second expression vector is transformed into a second haploid cell. The transformed haploid cells, each individually synthesizing a non-identical polypeptide, are … The mechanism of ammonia synthesis contains the following seven elementary steps: 1. transport of the reactants from the gas phase through the boundary layer to the surface of the catalyst. 2. pore diffusion to the reaction center
