DNA polymerase of mitochondria is a gamma-polymerase.

open access: yesJournal of Biological Chemistry, 1977
Mitochondria isolated from rat liver cells or mycoplasma-free HeLa cells contain a single DNA polymerase activity which is closely related to, or identical to, the DNA polymerase gamma activity found in the homologous cell. In rat liver cells, about 16% of the total cytoplasmic gamma-polymerase activity is found associated with mitochondria and in HeLa

LigD: A Structural Guide to the Multi-Tool of Bacterial Non-Homologous End Joining

open access: yesFrontiers in Molecular Biosciences, 2021
DNA double-strand breaks are the most lethal form of damage for living organisms. The non-homologous end joining (NHEJ) pathway can repair these breaks without the use of a DNA template, making it a critical repair mechanism when DNA is not replicating ...

DNA polymerase fidelity and the polymerase chain reaction. [PDF]

open access: yesGenome Research, 1991
High-fidelity DNA synthesis conditions are those that exploit the inherent ability of polymerases to discriminate against errors. This review has described several experimental approaches for controlling the fidelity of enzymatic DNA amplification. One of the most important parameters to consider is the choice of which polymerase to use in PCR.

Structure and mechanism of human DNA polymerase η [PDF]

open access: yes, 2010
The variant form of the human syndrome xeroderma pigmentosum (XPV) is caused by a deficiency in DNA polymerase eta (Pol eta), a DNA polymerase that enables replication through ultraviolet-induced pyrimidine dimers.

Functional Insights into ANP32A-Dependent Influenza A Virus Polymerase Host Restriction

open access: yesCell Reports, 2017
Host restriction of influenza A virus limits pandemic emergence. The viral RNA polymerase (vPol) is an essential enzyme that must adapt for avian viruses to replicate in humans. Species differences in host ANP32A dictate adaptation: human ANP32A lacks an

Preparation and functional evaluation of monoclonal antibodies targeting Hepatitis B Virus Polymerase

open access: yesVirulence, 2021
HBV pol plays a critical role in the replication of hepatitis B virus (HBV). Previous studies conducted on HBV pol have produced limited evidence on HBV pol expression due to the lack of effective detection methods.

Versatile SARS-CoV-2 Reverse-Genetics Systems for the Study of Antiviral Resistance and Replication

open access: yesViruses, 2022
The COVID-19 pandemic continues to threaten healthcare systems worldwide due to the limited access to vaccines, suboptimal treatment options, and the continuous emergence of new and more transmissible SARS-CoV-2 variants.
