should we have to be so restrictive as to include the word "symetrical" in
this definition. Are arrangements of subunits always symetrical? (I know
this is what the Monod-Wyman-Changeaux model of allosteric transitions
states, but...)
Maybe someone else can answer this question: "Are arrangements of subunits
always symetrical?"
