Hexameric assembly of MtaLonC.
(A) Molecular weight analysis of MtaLonC by analytical ultracentrifugation. Representative sedimentation equilibrium distribution of Mt-LonC suggested an average molecular weight of 462,476 Da, corresponding to hexamers in solution. (B) Representative class averages of negatively stained MtaLonC particles. Images such as 1, 15, 20, and 23 show the predominant top view of the hexameric complex. Images 3, 5, 7, and 27 may represent various side views of the assembly. The scale bar is 10 nm.
