Spectra of 20 μM MBP in 50 mM ammonium acetate pH7. (A) DP60 V, (B) DP 60 V in the presence of 20 μM MBP-9, (C) DP 180 V in the presence of 20 μM MBP-9, (D) DP 60 V in the presence of 20 μM MBP-9 and 20 μM maltose. In panel A the peaks are labeled by the charge acquired during the electrospray. In panels B-D the peaks corresponding to apoMBP (○), MBP:MBP-9 1:1 complex (•), MBP:MBP-9 1:2 complex (••), MBP:maltose 1:1 complex (gray solid circle) and MBP:MBP-9:maltose: 1:1:1 complex (black/gray solid circles) are labeled.
