This chapter describes the known members of archaeal protein-folding pathways, including not only the heat-shock-regulated members, but also the non-heat-shock-regulated protein chaperones. The major chaperone classes, heat shock protein (Hsp) 100 and Hsp90/Hsp83, are absent from the genomes of the hyperthermophilic archaea, although they are present in several mesophilic and thermophilic archaea. In archaea, with one exception, prefoldins are hexamers consisting of two α-subunits and four β-subunits, which act as generalized holding chaperones. The holding-and-release mechanism of the archaeal prefoldins has recently been elucidated. The archaeal group II chaperonins form toroidal double rings with an eightor ninefold symmetry, consisting of homologous subunits. The subunit composition of the chaperonin complexes in several archaea changes with growth temperature. The known properties, arrest and ATPase activity, and structural characteristics of archaeal chaperonins are provided in this chapter. The helical protrusion is strictly conserved among group II chaperonins. The existing evidence indicates that asymmetric and symmetric molecules are present in the functional ATPase cycle of archaeal group II chaperonins. The coexistence of both groups of chaperonins in the same cytosol in the Methanosarcina species provides a useful model system for studying the differential substrate specificities of the group I and II chaperonins, and for elucidating how newly synthesized proteins are sorted from the ribosome to the appropriate chaperonin for folding.
