5-Hydroxy-5-methylhydantoin DNA lesion, a molecular trap for DNA glycosylases
Oxford University Press (2011-04-12)DNA base-damage recognition in the base excision repair (BER) is a process operating on a wide variety of alkylated, oxidized and degraded bases. DNA glycosylases are the key enzymes which initiate the BER pathway by ... -
Bacterial base excision repair enzyme Fpg recognizes bulky N7-substituted-FapydG lesion via unproductive binding mode
(2012-07-18)Fpg is a bacterial base excision repair enzyme that removes oxidized purines from DNA. This work shows that Fpg and its eukaryote homolog Ogg1 recognize with high affinity FapydG and bulky N7-benzyl-FapydG (Bz-FapydG). The ... -
Coordination behaviour of new open chain and macrocyclic peptidomimetic compounds with copper (ii)
