additional information
hexamer
alpha6, organized as a dimer of trimers, crystal structure
hexamer
trimer of dimers, crystallization, the forces that hold the hexamer together are (a) hydrophobic interactions between the dimeric couples A + B, C + D and E + F (b) a few hydrogen bonds, and a hydrophobic interaction between A + C, B + E and D + F, and (c) electrostatic forces in the central channel of the hexamer between B, C and F, and A, D and E
calculations indicate a heptamer of the major form and a trimer of the minor one. Homoheptamers are not frequently observed and the major form may, rather, be a hexamer
