Figure 2. NH2-terminal acetylation profile for alligator and human rHbs that were synthesized using different plasmid systems.

Histograms depict the percentage of NH2-terminal acetylation for the α- and β-chain subunits and reveal that rHbs synthesized with the pGM + pMAP + pNatA expression plasmid resulted in successful addition of acetyl groups to the amino termini.
