Purinyl-cobamide is a native prosthetic group of reductive dehalogenases, Published online: 06 November 2017; doi:10.1038/nchembio.2512

NatureArticleSnippet(type=short-summary, markup=

In organohalide-respiring bacteria, reductive dehalogenases cleave carbon–halogen bonds using cobamide prosthetic groups. Desulfitobacterium hafniense uses an unprecedented cobamide variant, which includes unsubstituted purine, for this function.

Small molecule promotes β-catenin citrullination and inhibits Wnt signaling in cancer, Published online: 30 October 2017; doi:10.1038/nchembio.2510

NatureArticleSnippet(type=short-summary, markup=

The small molecule nitazoxanide (NTZ) was identified as a Wnt inhibitor by promoting protein citrullination of β-catenin through increased cytosolic calcium and PAD2 protein stabilization. β-catenin citrullination results in proteasomal degradation.
