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, B	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
