I am happy to share our latest publication. In this work, we show that OGG1 association with DNA during lesion search involves local DNA distortion promoting base unstacking. This process is tightly controlled by conserved residues to ensure stable association without compromising fast scanning.
A coordinated haptic mechanism ensures efficient DNA sampling by the 8-oxoguanine glycosylase OGG1
Please check our collaborative paper with Marcin Suskiewicz and Sebastien Huet labs on FAM118 proteins – non-canonical sirtuins that form filaments and act as NADases in human and other vertebrate cells. www.nature.com/articles/s41...
Filament formation and NAD processing by noncanonical human FAM118 sirtuins - Nature Structural & Molecular Biology
Baretić and Missoury et al. identify vertebrate proteins FAM118B and FAM118A as sirtuins similar to bacterial antiphage enzymes and show that FAM118A/B processing of NAD involves head-to-tail filament...
