Human red cell acetyltransferase

  • 1. Medical College of Georgia, Augusta (USA)

Description

Acetyltransferase was isolated by histone-Sepharose affinity chromatography from human cord blood red cells. The enzyme was detected only in very young red cells. The semipurified enzyme and [14C]acetyl-CoA were used to acetylate isolated Hb F tetramer and α and γ subunits. The in vitro acetylated products were characterized by globin chain separation by CM-cellulose chromatography and tryptic peptide analysis by reverse-phase HPLC. Acetylation of both the γ-chains and the α-chains could occur within the Hb F tetramer. Acetylation also could take place on intact subunits. It appears that some Hb F/sub Ic/ could be formed in the cells by utilizing Hb F or free γ-chains as acetylation substrate
