Also known as:

Comments: The crystal structure of Hb Kirklareli shows that the mutation creates a completely apolar active site, which prevents electrostatic stabilization of bound O2, promotes autoxidation, and enhances hemin dissociation by inhibiting water coordination to the Fe(III) atom.

We follow the HGVS sequence variant nomenclature and IUPAC standards.
