Unravelling the specificity and mechanism of sialic acid recognition by the gut symbiont Ruminococcus gnavus
(Nature Research, 2017)
Ruminococcus gnavus is a human gut symbiont wherein the ability to degrade mucins is mediated by an intramolecular trans-sialidase (RgNanH). RgNanH comprises a GH33 catalytic domain and a sialic acid-binding carbohydrate-binding ...
