WebOur results demonstrate that a reversible replication fork barrier allows induction of a synchronous and spatially defined termination event. They also show that soon after forks meet, as measured by dissolution, daughter molecules are quickly ligated and decatenated. Converging replication forks do not stall

WebApr 8, 2024 · DNA replication is mediated by the coordinated actions of multiple enzymes within replisomes. Processivity clamps tether many of these enzymes to DNA, allowing access to the primer/template junction. Many clamp-interacting proteins (CLIPs) are involved in genome maintenance pathways including translesion synthesis (TLS). WebDNA-protein interactions at the replication fork. The funda-mental reactions occurring at a T7 DNA replication fork can be reconstituted using four proteins, three encoded by T7, the products of genes 2.5, 4, and 5, and one protein, thioredoxin, which is encoded by E. coli (16).
