“Chaperonin GroEL uses asymmetric and symmetric reaction cycles in response to the concentration of non-native substrate proteins”

【Significance】
GroEL uses two types of reaction cycles in response to the concentration of non-native proteins

The chaperonin GroEL is a double-ring structure that assists protein folding in association with its cofactor GroES. It is widely accepted that an asymmetric GroEL−GroES complex is formed throughout the reaction cycle, whereas a symmetric GroEL−(GroES)2 complex is not formed. However, this conventional view has been challenged by the recent reports indicating that such symmetric complexes can be formed in the reaction cycle. We suggest that GroEL uses two types of reaction cycles (asymmetric or symmetric) in response to the concentration of non-native proteins.
