Biosynthesis of Chick Hemoglobins

Abstract

In vivo studies of the biosynthesis of chick hemoglobins 1 and 2 showed an over-all higher incorporation of glycine-2-C(14), valine-4-C(14), valine-1-C(14), leucine-G-C(14), and histidine-(2-ring)-C(14) in hemoglobin 2; in vitro studies made with intact nucleated chick erythrocytes showed the higher incorporation of glycine-2-C(14), valine-1-C(14), and histidine-(2-ring)-C(14) in hemoglobin 1. Hybridization of chick hemoglobins produced an electrophoretically distinguishable new component.
