Name  GroEL-like equatorial domain Short Name  GROEL-like_equatorial
Type  Domain Description  Chaperonins are large cylindrical structures that transiently enclose a partially folded polypeptide and allow it to continue folding in a sequestered environment. Chaperonins are grouped into two families: group I chaperonins, found in eubacteria (e.g. GroEL in Escherichia coli) and eukaryotic organellesof eubacterial descent (e.g. Cpn60 in mitochondria and chloroplasts), and group II chaperonins, found in archaea and the eukaryotic cytosol (CCT or TCP-1 complex) [, ]. Both groups share a common monomer architecture of three domains: an equatorial domain that carries ATPase activity, an intermediate domain, and an apical domain, involved in substratebinding [, , ].This entry represents the equatorial domain.
