Response of the replisome to araA and araC suggests a mechanism for arabinosyl nucleoside tolerance

Arabinosyl (ara) nucleoside analogues such as vidarabine (araA) and cytarabine (araC) are antimetabolites known to inhibit DNA polymerases in isolation. However, their effects on DNA synthesis catalysed by the multi-protein replisome remain unknown. Here, we uncover a central rol...
