Table 3.

Inter-atomic, inter-ring distances (Å) between E461(OE2) and R452(NH2) of GroEL in three structural states: wild-type and the mutant K105A that lacks negative cooperativity (entries 1 and 2), the asymmetric GroEL–GroES1 ‘bullet’ complex (entry 3) and the symmetric GroEL–GroES2 complex (entry 4).
