Analysis of recombinant azurin I. (a) The MALDI-ToF profiles of recombinant azurin (full line) and native azurin I (dotted line) are shown (see Experimental for details). The three most prominent peaks are highlighted. (b) Q-ToF of RecAz showing the four sets of doublets. The doublets are the Cu-containing and apo-forms of the protein. The four sets are consistent with up to three MES molecules binding to the protein. |
