Alexeeva, M., Moen, M.N., Grøsvik, K. et al (2018) Excision of uracil from DNA by hSMUG1 includes strand incision and processing.
Moen, Marivi Nabong; Grøsvik, Kristin; Kirpekar, Finn; Tesfahun, Almaz Nigatu; Ruoff, Peter; Klungland, Arne; Bjelland, Svein (Journal article; Peer reviewed, 2018-11)Uracil arises in DNA by hydrolytic deamination of cytosine (C) and by erroneous incorporation of deoxyuridine monophosphate opposite adenine, where the former event is devastating by generation of C → thymine transitions. ... -
Alleviation of C⋅C Mismatches in DNA by the Escherichia coli Fpg Protein
Tesfahun, Almaz Nigatu; Alexeeva, Marina; Tomkuvienė, Miglė; Arshad, Aysha; Guragain, Prashanna; Klungland, Arne; Klimašauskas, Saulius; Ruoff, Peter; Bjelland, Svein (Peer reviewed; Journal article, 2021-06)DNA polymerase III mis-insertion may, where not corrected by its 3′→ 5′ exonuclease or the mismatch repair (MMR) function, result in all possible non-cognate base pairs in DNA generating base substitutions. The most ... -
The escherichia coli alkA gene is activated to alleviate mutagenesis by an oxidized deoxynucleoside
Grøsvik, Kristin; Tesfahun, Almaz Nigatu; Muruzábal-Lecumberri, Izaskun; Haugland, Gyri Teien; Leiros, Ingar; Ruoff, Peter; Kvaløy, Jan Terje; Knævelsrud, Ingeborg; Ånensen, Hilde; Alexeeva, Marina; Sato, Kousuke; Matsuda, Akira; Alseth, Ingrun; Klungland, Arne; Bjelland, Svein (Peer reviewed; Journal article, 2020)The cellular methyl donor S-adenosylmethionine (SAM) and other endo/exogenous agents methylate DNA bases non-enzymatically into products interfering with replication and transcription. An important product is 3-methyladenine ... -
Intrinsic Strand-Incision Activity of Human UNG: Implications for Nick Generation in Immunoglobulin Gene Diversification
Alexeeva, Marina; Moen, Marivi Nabong; Xu, Xiang Ming; Rasmussen, Anette; Leiros, Ingar; Kirpekar, Finn; Klungland, Arne; Alsøe, Lene; Nilsen, Hilde; Bjelland, Svein (Peer reviewed; Journal article, 2021)Uracil arises in cellular DNA by cytosine (C) deamination and erroneous replicative incorporation of deoxyuridine monophosphate opposite adenine. The former generates C → thymine transition mutations if uracil is not removed ...
