Helicases are a class of enzymes thought to be vital to all organisms. Their main function is to unpack an organism's genetic material. Helicases are motor proteins that move directionally along a nucleic acid phosphodiester backbone, separating two hybridized nucleic acid strands (hence helic- + -ase), using … Meer weergeven Helicases are often used to separate strands of a DNA double helix or a self-annealed RNA molecule using the energy from ATP hydrolysis, a process characterized by the breaking of hydrogen bonds Meer weergeven Helicases are classified in 6 groups (superfamilies) based on their shared sequence motifs.

WebTFIIH is a large protein complex that contains among others the CDK7 / cyclin H kinase complex and a DNA helicase. TFIIH has three functions: It binds specifically to the template strand to ensure that the correct strand of DNA is transcribed and melts or unwinds the DNA ( ATP -dependent) to separate the two strands using its helicase activity.
