This domain is found at the C-terminal region of Heat resistant RNA dependent ATPase from Thermus thermophilus (also known as Hera) the first DEAD box helicase that forms a stable dimer in the absence of ligands. This dimerization domain (DD) folds into a single turn of a left-handed super-helix [1,2].	Domain
A	PF00271	Helicase conserved C-terminal domain (Helicase_C)	Helicase conserved C-terminal domain	The Prosite family is restricted to DEAD/H helicases, whereas this domain family is found in a wide variety of helicases and helicase related proteins. It may be that this is not an autonomously folding unit, but an integral part of the helicase.	Domain

This domain is found at the C-terminal end DEAD box helicase Hera from Thermus thermophilus. This entry represents the RNA binding domain, which is located C-terminal to the dimerisation domain Pfam:PF21591. This domain is responsible for binding of Hera to 23S rRNA. It consists of a central four-stranded beta-sheet, flanked by an alpha-helix, and a long loop connecting beta-strands 3 and 4 that replaces helix alpha2 present in canonical RNA recognition motif (RRM) [1,2].
