Biosynthesis of rainbow trout (Salmo gairdnerii) hemoglobins in vitro.
Cell free systems were established to analyze the biosynthesis of trout hemoglobins I, II and III. HbI, II and III were synthesized in trout erythroid cell lysates as well as in a mRNA dependent rabbit reticulocyte lysate supplemented with trout erythroid cell polyA-RNA. The newly synthesized hemoglobins apparently contained the N alpha-acetyl modification at their alpha-chain amino terminals since they co-migrated with carrier trout hemoglobins that are known to contain the modification. This observation suggests that the acetylation is determined by the information encoded in the mRNA.
