abstract：:Rad18 is a ubiquitin E3 ligase that monoubiquitinates PCNA on stalled replications forks. This allows recruitment of damage-tolerant polymerases for damage bypass and DNA repair. In this activity, the Rad18 protein has to interact with Rad6, the E2 ubiquitin-conjugating enzyme, ubiquitin, PCNA and DNA. Here we analyze...

abstract：:Lysinomicin, a naturally-occurring pseudodisaccharide, inhibits translation in prokaryotes. We report that lysinomicin (and three related compounds) are able to inhibit the self-splicing of group I introns, thus identifying pseudodisaccharides as a novel class of group I intron splicing inhibitors. Lysinomicin inhibit...
