"TriC/CCT-mediated beta-actin folding involves rapid ATP-independent formation of a binary complex, followed by a slower ATP-dependent release of the native product (Gao et al., 1992). Group II chaperonins enclose substrate proteins following substrate binding through the formation of a \"built- in\" lid over the central cavity. Upon ATP binding, lid formation is triggered by the transition state of ATP hydrolysis (Meyer, et al., 2003)."^^ . . . . . . .
