Metabolite Identification
Common NameTundrenone
DescriptionTundrenone is a secondary metabolite belonging to the class of highly oxidized compounds. Its chemical structure features a modified bicyclic chorismate-derived fragment and a lipid tail that includes a β,γ-unsaturated α-hydroxy ketone. Tundrenone is produced by the methanotrophic bacterium Methylobacter tundripaludum, where its biosynthesis is genetically linked to specific biosynthetic gene clusters and is activated through quorum sensing mechanisms. This metabolite plays a role in a complex hypoxia response system unique to Methylobacter species, involving interactions with nitric oxide and central carbon metabolism pathways, as well as denitrification processes. The intricate relationship between tundrenone and the NO-mediated stress response highlights its potential significance in the environmental fitness and distribution of these bacteria. Furthermore, bioinformatic analyses of Methylobacter tundripaludum's genome suggest that tundrenone is part of a broader array of intriguing metabolites, indicating that further research into methane-oxidizing bacteria may uncover additional novel molecular scaffolds and their corresponding biosynthetic pathways (PMID:31964770 , PMID:29532849 , PMID:29361220 ).
