A 13C-NMR study of mutant hemoglobins with altered oxygen affinity
Abstract:
The 13CO-NMR spectra of carbonylhemoglobins Saint Mandé (beta 102Asn----Tyr), Malmö (beta 97His----Gln), Hôtel Dieu (beta 99Asp----Gly) and Ao have been determined. The positions of the 13CO resonances for hemoglobins Ao, Malmö and Hôtel Dieu were similar indicating similar ligand environments for all. The 13CO resonance for the beta-subunit of Saint Mandé was upfield-shifted compared to the others. This is evidence that structural changes at the beta 102 position directly affect iron-ligand bonding as well as quaternary structure.

Globular and Fibrous Proteins
Globular proteins are also known as spheroproteins and typically are approximately round in shape. They contain a mix of amino acid types and contain differing sequences in their primary structures. Globular proteins have many different functions, such as enzymes, cellular messengers, and molecular transporters. These roles often require the proteins to be...
