Resumo(s)
Haem proteins are one of the most versatile groups of proteins in nature. They
are able to perform several functions, such as transport and storage of oxygen, electron
transfer, sensing of small molecules, and catalysis. The nature of the haem, the
presence or absence and the nature of the axial ligands to the iron atom, and the effect
of the polypeptide chain of the protein on the environment of the haem all contribute
to this versatility. The work presented in this thesis focuses on the mechanisms of
electron transfer and the discrimination of small ligands by cytochromes containing
haem c with axial histidines.(...)
