Bacterial Helicases

Journal of Structural Biology, 1998
Helicases are proteins that use the energy of ATP hydrolysis to open double-stranded DNA, RNA, or RNA-DNA hybrids into two single strands. Based upon sequence analysis, at least 12 helicases exist in Escherichia coli. We know that these proteins play important roles in DNA replication, recombination, repair, and transcription, as well as in RNA ...

Helicases and aging

Cellular and Molecular Life Sciences (CMLS), 2000
Studying monogenic hereditary disorders that manifest age-related phenotypes in cells, tissues, and the total organism would be helpful for clarifying the mechanisms of aging. In this context, seven human disorders that manifest age-related phenotypes have been found to be caused by aberrations of five proteins with seven helicase motifs conserved in ...

Helicase associated 2 domain is essential for helicase activity of RNA helicase A

Biochimica et Biophysica Acta (BBA) - Proteins and Proteomics, 2014
RNA helicase A (RHA), a DExD/H box protein, plays critical roles in a wide variety of cellular or viral functions. RHA contains a conserved core helicase domain that is flanked by five other domains. Two double-stranded RNA binding domains (dsRBD1 and dsRBD2) are at the N-terminus, whereas HA2 (helicase associated 2), OB-fold (oligonucleotide- or ...

Helicases: An Overview

2009
Helicases are essential enzymes involved in all aspects of nucleic acid metabolism including DNA replication, repair, recombination, transcription, ribosome biogenesis and RNA processing, translation, and decay. They occur in vivo as part of molecular complexes that include the components required for each specific step of nucleic acid metabolism.
