Deep Sequencing Analysis of RNAs from Citrus Plants Grown in a Citrus Sudden Death-Affected Area Reveals Diverse Known and Putative Novel Viruses. [PDF]
, 2017 Citrus sudden death (CSD) has caused the death of approximately four million orange trees in a very important citrus region in Brazil. Although its etiology is still not completely clear, symptoms and distribution of affected plants indicate a viral ...

The embryonic RNA helicase gene (ERH): a new member of the DEAD box family of RNA helicases [PDF]
Biochemical Journal, 1995 DEAD box proteins share several highly conserved motifs including the characteristic Asp-Glu-Ala-Asp (D-E-A-D in the amino acid single-letter code) motif and have established or putative ATP-dependent RNA helicase activity. These proteins are implicated in a range of cellular processes that involve regulation of RNA function, including translation ...

Bio-Protocol, 2014 Helicases are a class of enzymes which are motor proteins using energy derived from ATP hydrolysis to move directionally along a nucliec acid phosphodiester backbone (such as DNA, RNA and DNA-RNA hybrids) and separate two annealed nucleic acid strands ...

Conserved motifs in the flavivirus NS3 RNA helicase enzyme
Wiley Interdisciplinary Reviews - RNA, 2021 Flaviviruses are a major health concern because over half of the world population is at risk of infection and there are very few antiviral therapeutics to treat diseases resulting from infection.

Nuclear DNA Helicase II (RNA Helicase A) Interacts with Werner Syndrome Helicase and Stimulates Its Exonuclease Activity [PDF]
Journal of Biological Chemistry, 2005 Nuclear DNA helicase II (NDH II), alternatively named RNA helicase A, is involved in transcription and RNA processing. Here, we report that NDH II interacts with the Werner syndrome helicase WRN, an enzyme associated with premature aging and predisposition to tumorigenesis.

PLoS Pathogens, 2019 Positive-stranded RNA viruses replicate inside cells and depend on many co-opted cellular factors to complete their infection cycles. To combat viruses, the hosts use conserved restriction factors, such as DEAD-box RNA helicases, which can function as ...

mBio, 2018 Present in every kingdom of life, generally in multiple copies, DEAD-box RNA helicases are specialized enzymes that unwind RNA secondary structures. They play major roles in mRNA decay, ribosome biogenesis, and adaptation to cold temperatures.

Structural biology of ferritin nanocages
FEBS Letters, EarlyView.Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...
