General Information | Comment | Organism |
---|---|---|
evolution | the enzyme belongs to the group II chaperonins, which are found in archaeal (thermosome of Thermoplasma acidophilum) and in eukaryotic (chaperonin-containing TCP-1 or CCT) species, have eight or nine subunits per ring made of two (thermosome) or eight (CCT) types of subunits. Subunit heterogeneity in group II chaperonins, found primarily within the apical domains, has important consequences for the functional specialization of ring components, role of heterogeneity in subunit dynamics. Nonconservation of intra-ring cooperativity among chaperonin classes, overview | Thermoplasma acidophilum |
additional information | three-dimensional structures of nucleotide states of thermosome and allosteric communications within the archaeal chaperonin thermosome, open and closed states and transitional conformation changes, computational analysis, overview | Thermoplasma acidophilum |
physiological function | chaperonins are molecular machines that use ATP-driven cycles to assist misfolded substrate proteins to reach the native state. During the functional cycle, these machines adopt distinct nucleotide-dependent conformational states, which reflect large-scale allosteric changes in individual subunits. Archaeal and eukaryotic chaperonins undergo sequential subunit motions, analysis of the mode of action and mechanism. The thermosome double-ring structure has large contribution from higher-frequency modes | Thermoplasma acidophilum |
