Domain orientation in the RNA helicase YxiN and the role of conformational changes for RNA unwinding [PDF]
, 2010 The RNA helicase YxiN from Bacillus subtilis is a member of the family of DEAD box proteins. YxiN is able to unwind RNA double strands in an ATP-dependent manner. The ability to catalyse RNA rearrangement is in vivo presumably necessary for the bacterial

The emerging role of DEAD/H-box helicases in hepatitis B virus infection
Frontiers in Cellular and Infection Microbiology, 2022 DEAD/H-box helicases are an essential protein family with a conserved motif containing unique amino acid sequences (Asp-Glu-Ala-Asp/His). Current evidence indicates that DEAD/H-box helicases regulate RNA metabolism and innate immune responses.

Visualizing helicases unwinding DNA at the single molecule level. [PDF]
, 2010 DNA helicases are motor proteins that catalyze the unwinding of double-stranded DNA into single-stranded DNA using the free energy from ATP hydrolysis. Single molecule approaches enable us to address detailed mechanistic questions about how such enzymes ...

Structural Basis of DEAH/RHA Helicase Activity
Crystals, 2017 DEAH/RHA helicases are members of a large group of proteins collectively termed DExH-box, which also include Ski2-like and NS3/NPH-II helicases. By binding and remodeling DNA and RNA, DEAH/RHA helicases play critical roles in many cellular processes ...

LGP2 plays a critical role in sensitizing mda-5 to activation by double-stranded RNA. [PDF]
, 2013 The DExD/H box RNA helicases retinoic acid-inducible gene-I (RIG-I) and melanoma differentiation associated gene-5 (mda-5) sense viral RNA in the cytoplasm of infected cells and activate signal transduction pathways that trigger the production of type I ...

RNA helicases in infection and disease [PDF]
RNA Biology, 2012 RNA helicases unwind their RNA substrates in an ATP-dependent reaction, and are central to all cellular processes involving RNA. They have important roles in viral life cycles, where RNA helicases are either virus-encoded or recruited from the host. Vertebrate RNA helicases sense viral infections, and trigger the innate antiviral immune response.
