Enhancement of recombinant hemoglobin production in Escherichia coli BL21(DE3) containing the Plesiomonas shigelloides heme transport system.
To produce recombinant hemoglobin in Escherichia coli, sufficient intracellular heme must be present, or the protein folds improperly and is degraded. In this study, coexpression of human hemoglobin genes and Plesiomonas shigelloides heme transport genes enhanced recombinant hemoglobin production in E. coli BL21(DE3) grown in medium containing heme.
