Structures of haemoglobin from woolly mammoth in liganded and unliganded states

The haemoglobin (Hb) of the extinct woolly mammoth has been recreated using recombinant genes expressed in Escherichia coli. The crystal structures of mammoth Hb have been determined in the deoxy, carbonmonoxy and aquo-met forms.
