Interactions between fungal glutathione transferases and wood extractives
2017 - IRG/WP 17-10894
The interactions between extractives from several tree species of French Guyana and glutathione transferases (GST) from the white-rot Trametes versicolor have been studied. These interactions have been monitored using a thermal shift assay. It appears from these experiments that TvGSTO2S interacts strongly with acetonic extract of Bagassa guianensis and in particular with oxyresveratrol. In agreem...

Interactions between wood polyphenols and detoxification enzymes of the white rot Trametes versicolor
2018 - IRG/WP 18-10906
Wood decay fungi have complex detoxification systems that enable them to cope with secondary metabolites produced by plants. Although the number of genes encoding for glutathione transferases (GSTs) is especially expanded in lignolytic fungi, little is known about their physiological target molecules. In this study, by combining thermal shift assay and affinity crystallography we highlighted inter...

From fungal detoxification systems to wood durability in neotropical forests
2019 - IRG/WP 19-10946
White-rot fungi are able to mineralize all the wood components due in particular to an efficient detoxification system. We hypothesised that components of this detoxification systems, glutathione transferases, could be used as tools to explore the natural durability of neotropical wood species. Analysis of the interactions between six glutathione transferases of Trametes versicolor and extracts of...
