AI Article Synopsis
- Researchers studied cyanobacterial dialkylresorcinol bartolosides, initially thought to have glycosylated and halogenated structures.
- They found that these compounds can form esters through a process involving chlorinated alkyl chains and fatty acids, leading to a variety of bartoloside derivatives.
- The study identified 27 bartoloside and ester variants, including two new types, and revealed new structural features like hydroxylation that were not previously linked to this metabolite group.
Article Abstract
The cyanobacterial dialkylresorcinol bartolosides were initially reported to feature glycosylated and halogenated moieties. Later, biosynthetic and studies showed that the chlorinated alkyl chains are utilized for a nucleophilic substitution with free fatty acid carboxylates from primary metabolism, generating bartoloside esters. Here, we applied a workflow based on PCR screening coupled to LC-HRESIMS and molecular network analysis with the aim of discovering additional bartoloside diversity. We report the annotation of 27 bartoloside and bartoloside ester derivatives, including the characterization of two new bartolosides, underlining the breadth of structures generated by bartoloside biosynthetic pathways. Some of the herein reported bartolosides feature hydroxylation in their side chains, a modification that has not been associated with this metabolite family.

Background: Halogenation is a recurring feature in natural products, especially those from marine organisms. The selectivity with which halogenating enzymes act on their substrates renders halogenases interesting targets for biocatalyst development. Recently, CylC - the first predicted dimetal-carboxylate halogenase to be characterized - was shown to regio- and stereoselectively install a chlorine atom onto an unactivated carbon center during cylindrocyclophane biosynthesis.

Covering: up to 2019 Alkylresorcinols are amphiphilic metabolites, well-known for their diverse biological activities, produced by both prokaryotes and eukaryotes. A few classes of alkylresorcinol scaffolds have been reported from the photoautotrophic cyanobacteria, ranging from the relatively simple hierridins to the more intricate cylindrocyclophanes. Recently, it has emerged that cyanobacteria employ two different biosynthetic pathways to produce unique alkylresorcinol scaffolds.

The isolation of the bartolosides, unprecedented cyanobacterial glycolipids featuring aliphatic chains with chlorine substituents and C-glycosyl moieties, is reported. Their chlorinated dialkylresorcinol (DAR) core presented a major structural-elucidation challenge. To overcome this, we discovered the bartoloside (brt) biosynthetic gene cluster and linked it to the natural products through in vitro characterization of the DAR-forming ketosynthase and aromatase.
