Helicase polarity, which is also deemed "directionality", is defined as the direction (characterized as 5'→3' or 3'→5') of helicase movement on the DNA/RNA single-strand along which it is moving. This determination of polarity is vital in f.ex. determining whether the tested helicase attaches to the DNA leading strand, or the DNA lagging ...

Probable ATP-dependent RNA helicase DDX5 also known as DEAD box protein 5 or RNA helicase p68 is an enzyme that in humans is encoded by the DDX5 gene. [ 5 ] Function
Functions as an enzymatically active RNA molecule. RNA polymerase is essential to life, and is found in all living organisms and many viruses . Depending on the organism, a RNA polymerase can be a protein complex (multi-subunit RNAP) or only consist of one subunit (single-subunit RNAP, ssRNAP), each representing an independent lineage.
ATP-dependent RNA helicase DDX3X is an enzyme that in humans is encoded by the DDX3X gene. [5] [6] [7] ... DDX3X performs its functions in the cell nucleus and ...
A Rho factor acts on an RNA substrate. Rho's key function is its helicase activity, for which energy is provided by an RNA-dependent ATP hydrolysis. The initial binding site for Rho is an extended (~70 nucleotides, sometimes 80–100 nucleotides) single-stranded region, rich in cytosine and poor in guanine, called the rho utilisation site (rut), in the RNA being synthesised, upstream of the ...
Dicer, also known as endoribonuclease Dicer or helicase with RNase motif, is an enzyme that in humans is encoded by the DICER1 gene.Being part of the RNase III family, Dicer cleaves double-stranded RNA (dsRNA) and pre-microRNA (pre-miRNA) into short double-stranded RNA fragments called small interfering RNA and microRNA, respectively.
DEAD box proteins were first brought to attention in the late 1980s in a study that looked at a group of NTP binding sites that were similar in sequence to the eIF4A RNA helicase sequence. [4] The results of this study showed that these proteins (p68, SrmB, MSS116, vasa, PL10, mammalian eIF4A, yeast eIF4A) involved in RNA metabolism had several ...
