Hold tight (but not too tight) to get it right: accurate bypass of an 8-oxoguanine lesion by DNA polymerase beta

Structure. 2003 Jan;11(1):1-2. doi: 10.1016/s0969-2126(02)00917-6.

Abstract

Crystal structures of DNA polymerase beta encountering an 8-oxoguanine lesion show how the polymerase selects an otherwise unfavorable conformation of a damaged template base to enable error-free bypass.
