Description
A model for (low spin) hemoproteins and ferredoxin which takes into account both the fractal structure of the protein backbone (polypeptide chain) and the cross-connections (H-bridges) between segments of the folded chain is proposed. Within this picture the fracton dimensionality d sub(fr) (recently introduced by Alexander and Orbach), the fractal dimensionality d sub(f) and the Stapleton et al. experimental non-integer exponent n (spin-lattice relaxation rate 1/T1 proportional to T sup(n)) become satisfactorily consistent.

Propoe-se um modelo para hemoproteinas e ferredoxinas (baixo spin) que levam em conta tanto a estrutura fractal da espinha da proteina (cadeia polipeptidica) quanto as conexoes cruzadas (pontes H) entre os segmentos da cadeia dobrada. Dentro dessa visao a dimensionalidade do 'fracton' d sub(fr) (recentemente introduzida por Alexander e Orbach), a dimensionalidade fractal d sub(f) e o expoente nao inteiro experimental de Stapleton e colaboradores n (taxa de relaxacao spin-rede 1/T1 proporcional a T sup(n)) tornam-se satisfatoriamente consistentes.
