Abstract excerpt
The wild-type (WT) GH2-N ovine growth hormone (oGH) and duplicated GH2-Z genes differ in their open reading frame by two nonsynonymous substitutions, predicting a two-amino-acid difference in their product (G9R/G63S). Three recombinant oGH muteins: G9R, G63S and G9R/G63S, were prepared by site-directed mutagenesis of the WT oGH gene, expressed in E. coli, refolded and purified as monomers with over 98%...
