Members of this family include the DEAD and DEAH box helicases. Helicases are involved in unwinding nucleic acids. The DEAD box helicases are involved in various aspects of RNA metabolism, including nuclear transcription, pre mRNA splicing, ribosome biogenesis, nucleocytoplasmic transport, translation, RNA decay and organellar gene expression.

This domain is found in Large helicase-related protein from Escherichia coli (Lhr), DEAD/DEAH box helicase from Mycolicibacterium smegmatis (Swiss:A0QT91) and similar prokaryotic sequences. Lhr is a DNA damage-inducible superfamily 2 helicase that uses adenosine triphosphate (ATP) hydrolysis to drive unidirectional 3' to 5' translocation along single -stranded DNA (ssDNA) [1]. These proteins have an N-terminal helicase domain (Lhr-Core) and a C-terminal domain (Lhr-CTD). This entry represents the third domain in the Lhr-Core, which has a winged helix (WH) domain fold [1,2]. It is found associated to Pfam:PF00270 and Pfam:PF00271.	Domain
