title: Riding the (mono)rails: the structure of catenated DNA-tracking proteins.
abstract: New evidence suggests that the 'sliding clamp' processivity factors of DNA polymerases can carry a variety of protein factors along the DNA 'track'. Recent information on the structure of these factors sheds light on how they slide on DNA and why they confer processivity.
