Importance of base-pair opening for mismatch recognition [PDF]
Nucleic Acids Research, 2020 AbstractMismatch repair is a highly conserved cellular pathway responsible for repairing mismatched dsDNA. Errors are detected by the MutS enzyme, which most likely senses altered mechanical property of damaged dsDNA rather than a specific molecular pattern.

Alleviation of C⋅C Mismatches in DNA by the Escherichia coli Fpg Protein
Frontiers in Microbiology, 2021 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.

Spontaneous and frequent conformational dynamics induced by A…A mismatch in d(CAA)·d(TAG) duplex
Scientific Reports, 2021 Base pair mismatches in DNA can erroneously be incorporated during replication, recombination, etc. Here, the influence of A…A mismatch in the context of 5′CAA·5′TAG sequence is explored using molecular dynamics (MD) simulation, umbrella sampling MD ...

SPR fingerprinting of mismatched base pair [PDF]
Nucleic Acids Symposium Series, 2004 Discrimination of mismatched base pairs having various flanking sequence from normal Watson-Crick base pairs were examined using SPR sensor surface where mismatch binding ligand (MBL) were immobilized. CC, CT, and TT mismatched base pair are distinguishable from wild type DNA by means of diaminonaphthyndine dimer (damND) immobilized sensor surface.

ATP-Dependent Mismatch Recognition in DNA Replication Mismatch Repair
Quantum Reports, 2023 Mismatch repair is a critical step in DNA replication that occurs after base selection and proofreading, significantly increasing fidelity. However, the mechanism of mismatch recognition has not been established for any repair enzyme.
