Chains	Accession	Name	Description	Comments	Source
A, B	PF12344	Ultra-violet resistance protein B (UvrB)	Ultra-violet resistance protein B	-	Family
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
