Fig. 1

Ribbon diagram of MttB hexamer viewed along (a) the threefold axis with dimer pairs in more similar colors (yellow, orange; cyan, blue; violet, red); and (b) the twofold axis with one subunit colored orange, and the other subunit colored by region: residues 2–22 in blue, 23–81 in green, TIM-barrel 82–395 in yellow, dimerization loop 396–452 in magenta, and 453–495 in red. Pyl334 is shown as red stick. c Structure of single subunit in ribbons colored as in (b). d Surface electrostatic potentials of single subunit with positive in blue (10 kcal/mol·e) and negative in red (−10 kcal/mol·e) in the same orientation as in (c).
