Abstract:
... RipAY, an effector protein from the plant bacterial pathogen Ralstonia solanacearum, exhibits γ-glutamyl cyclotransferase (GGCT) activity to degrade the host cellular glutathione (GSH) when stimulated by host eukaryotic-type thioredoxins (Trxs). Aave_4606 from Acidovorax citrulli, the causal agent of bacterial fruit blotch of cucurbit plants, shows significant homology to RipAY. Based on its homol ...

Abstract:
... Monocopper lytic polysaccharide monooxygenases (LPMOs) catalyse oxidative cleavage of glycosidic bonds in a reductant‐dependent reaction. Recent studies indicate that LPMOs, rather than being O₂‐dependent monooxygenases, are H₂O₂‐dependent peroxygenases. Here, we describe SscLPMO10B, a novel LPMO from the phytopathogenic bacterium Streptomyces scabies and address links between this enzyme’s cataly ...
