“…Homologs of kaiB and kaiC genes also exist in other Bacteria and even Archaea, where a shortend KaiC most often resembles only one domain [55]. An archaeal one-domain KaiC homolog was shown to form a hexameric ring, similar to the two duplicated domains of Synechococcus 7942 KaiC [60]. In Haloferax volcanii the transcripts of four kaiC homologs display diurnal accumulation profiles [61].…”

“…Very recently, KaiC proteins from the hyperthermophiles Thermococcus litoralis and Pyrococcus horikoshii were shown to be capable of KaiA-independent autophosphorylation at both 30°C and 75°C (34,39). Finally, structural analysis of a distinct family of archaea-specific uncharacterized proteins (DUF835, PF05763 in the Pfam database [40]) has shown that these proteins are inactivated ATPases that are most closely related to KaiC (41). Thus, currently, at least two additional protein families can be included in the archaeal KaiC group (Fig.…”

“…In vivo functional analyses have shown that two archaeal homologs, RadC1 and RadC2, in S. islandicus are involved in DNA repair [81], though the exact role of RadC1 in HR is still under debate [66,79,82]. Crystal structures of several RadC proteins have been resolved [82,83]. RadC proteins form a hexamer ring structure with ADP and the ADP is located at the interface of monomers, a structure characteristic for many known biomotors.…”
