Hb Okazaki [beta 93(F8) Cys----Arg], a new hemoglobin variant with increased oxygen affinity and instability

FEBS Lett. 1984 Jul 23;173(1):45-7. doi: 10.1016/0014-5793(84)81014-5.

Abstract

A new abnormal hemoglobin, Hb Okazaki [beta 93(F9) Cys----Arg], with an amino acid substitution at the tyrosine pocket of the beta chain as well as at the alpha 2 beta 1 contact of the quaternary structure of molecule, was discovered in a Japanese man. This hemoglobin showed increased oxygen affinity and molecular instability.
