The approach of non-covalent conjugation has recently been used and a number of metal complexes have been encaged in a protein scaffold to form functional metallo proteins. Here we investigate a novel artificial superoxide dismutase enzyme based on the non-covalent conjugation of bovine serum albumin and the manganese(III) complex of N,N'-bis(salicylidene)-3,4-diaminobenzoic acid. We report the intriguing ability of the albumin environment to increase the SOD activity of the inorganic complex. We also determined the binding constant with BSA by CD spectroscopy.

Abstract
The approach of non-covalent conjugation has recently been used and a number of metal complexes have been encaged in a protein scaffold to form functional metallo proteins. Here we investigate a novel artificial superoxide dismutase enzyme based on the non-covalent conjugation of bovine serum albumin and the manganese(III) complex of N,N'-bis(salicylidene)-3,4-diaminobenzoic acid. We report the intriguing ability of the albumin environment to increase the SOD activity of the inorganic complex. We also determined the binding constant with BSA by CD spectroscopy.
