Oak Ridge National Lab highlights our recent work on pathways for conformational switching in high fidelity DNA polymerases: “Simulations reveal Nature’s design for error correction during DNA replication“.
Congratulation to Chunli Yan and Tom Dodd who published a new paper in the journal Nature Structural & Molecular Biology on the molecular architecture and functional dynamics of the transcription preinitiation complex (PIC). Yan, C.; Dodd, T.; Tainer, J.A.; He, Y.; Tsutakawa, S.E.; & Ivanov, I.* Transcription preinitiation complex structure and dynamics provide insight into genetic diseases Nature Structural […]
Our project on the base extrusion mechanism of thymine DNA glycosylase (TDG) was highlighted by the San Diego Supercomputer Center. How an Enzyme Repairs DNA via a “Pinch-Push-Pull” Mechanism
Congratulation to Tom Dodd, Chunli Yan, Kurt Martin and Brad Kossmann who published a new paper in the journal Proceedings of the National Academy of Sciences USA. Dodd, T.; Yan, C.; Kossmann, B.R.; Martin, K.; & Ivanov I.

Ivaylo visited Lawrence Berkeley National Lab in Feb. 2018 and gave a talk “DNA sculpting as a strategy for base extrusion and damage selection by the repair glycosylase TDG” at the Advanced Light Source synchrotron facility.
Ivaylo gave a talk “DNA sculpting as a strategy for base extrusion and damage selection by the repair glycosylase TDG” at the 3rd DNA Replication/Repair Structures and Cancer Conference in Cancun Mexico.
Our paper ‘Alkylpurine Glycosylase D Employs DNA Sculpting as a Strategy to Extrude and Excise Damaged Bases’ was published in PLOS Computational Biology. We employed chain-of-replicas path optimization strategy to determine a minimum energy path (MEP) for flipping out a 3-methyl adenine lesion by the DNA glycosylase AlkD. The path showed that AlkD acts by […]
