title: Bryn Bridges and mutagenesis: exploring the intellectual space.
abstract: The products of the SOS-regulated umuDC genes are required for most UV and chemical mutagenesis in Escherichia coli. Recently it has been recognized that UmuC is the founding member of a superfamily of novel DNA polymerases found in all three kingdoms of life. Key findings leading to these insights are reviewed, placing a particular emphasis on contributions made by Bryn Bridges and on his interest in the importance of interactions between the umuDC gene products and the replicative DNA polymerase.
