RNA polymerase pushing [PDF]

open access: yesBiophysical Chemistry, 2011
Molecular motors can exhibit Brownian ratchet or power stroke mechanisms. These mechanistic categories are related to transition state position: An early transition state suggests that chemical energy is stored and then released during the step (stroke) while a late transition state suggests that the release of chemical energy rectifies thermally ...

Plant DNA Polymerases [PDF]

open access: yesInternational Journal of Molecular Sciences, 2019
Maintenance of genome integrity is a key process in all organisms. DNA polymerases (Pols) are central players in this process as they are in charge of the faithful reproduction of the genetic information, as well as of DNA repair. Interestingly, all eukaryotes possess a large repertoire of polymerases.

RNA Polymerases of Maize: Nuclear RNA Polymerases [PDF]

open access: yesProceedings of the National Academy of Sciences, 1971
Two DNA-dependent RNA polymerases of nuclear origin have been purified from leaves of Zea mays . The two enzymes can be separated on DEAE-cellulose columns. Enzymes I and II are eluted with 0.08 and 0.20 M (NH 4 ) 2 SO 4 , respectively.

Chronic Hepatitis B Treatment Strategies Using Polymerase Inhibitor-Based Combination Therapy

open access: yesViruses, 2021
Viral polymerase is an essential enzyme for the amplification of the viral genome and is one of the major targets of antiviral therapies. However, a serious concern to be solved in hepatitis B virus (HBV) infection is the difficulty of eliminating ...

DNA Helicase–Polymerase Coupling in Bacteriophage DNA Replication

open access: yesViruses, 2021
Bacteriophages have long been model systems to study the molecular mechanisms of DNA replication. During DNA replication, a DNA helicase and a DNA polymerase cooperatively unwind the parental DNA.

Purification and Biochemical Characterisation of Rabbit Calicivirus RNA-Dependent RNA Polymerases and Identification of Non-Nucleoside Inhibitors

open access: yesViruses, 2016
Rabbit haemorrhagic disease virus (RHDV) is a calicivirus that causes acute infections in both domestic and wild European rabbits (Oryctolagus cuniculus). The virus causes significant economic losses in rabbit farming and reduces wild rabbit populations.
