The effect of inositol hexaphosphate on the absorption spectra of alpha and beta chains in nitrosyl hemoglobin.

K Nishikura, Y Sugita.   

Abstract

The spectral changes of nitrosyl hemoglobin on addition of inositol hexaphosphate were studied in hybrid-heme hemoglobins. The results showed that the decrease in absorption in the Soret region was mainly due to a spectral change in alpha chains, and that the tension on heme in the quaternary T structure was much stronger in alpha than in beta chains.
