1 Inter-ring communication is disrupted in the GroEL mutant Arg13 --> Gly; Ala126 --> Val with known crystal structure. Glycine heat shock protein family D (Hsp60) member 1 Homo sapiens
2 The crystal structures of the chaperonin GroEL Arg13 --> Gly; Ala126 --> Val double mutant, without and in complex with ATP gamma S, have been determined at atomic resolution. Glycine heat shock protein family D (Hsp60) member 1 Homo sapiens
3 Here, we show that the double mutation Arg13 --> Gly; Ala126 --> Val disrupts negative co-operativity between GroEL rings, with respect to ATP, but has little effect on the positive co-operativity within each ring. Glycine heat shock protein family D (Hsp60) member 1 Homo sapiens
