Clamping loader
Web摘要：. Recently, we revealed the architecture of the clamp-loader-helicase (tau-DnaB) complex in Bacillus by atomic force microscopy imaging and constructed a structural model, whereby a pentameric clamp-loader interacts with the hexameric helicase. Crucial to this model is the assumption that the clamp-loader forms a pentamer in the ...

WebA short overview of how DNA polymerase is locks onto DNA via the clamp and clamp loader WebSep 29, 2024 · Abstract. Clamp loaders load ring-shaped sliding clamps onto DNA where the clamps serve as processivity factors for DNA polymerases. In the first stage of clamp loading, clamp loaders bind and stabilize clamps in an open conformation, and in the second stage, clamp loaders place the open clamps around DNA so that the clamps …
