... attributed to the dissimilarity of the startingspecies CD spectra, and in the case of MT4, to the minor contribution at 350(+) nm assigned to the binding of Cu(I) to the bMT4 domain [16]. This ... [16]. In view of the distinct evolutionary patternsfollowed by MTs in birds and mammals, we decidedto focus our interest on the determination of the metalcoordination features of ckMT, using the ... determination of the spectroscopic and spectrometric features of the Zn-, Cd- and Cu- complexes rendered by the recom-binant full-length protein and its separate b and adomains, as well as of the...
