The intestinal microbiota influences many host biological processes, including metabolism, intestinal barrier functions, and immune responses in the gut and distant organs. Alterations in its composition have been associated with the development of inflammatory disorders and cardiovascular diseases, including Kawasaki disease (KD). KD is an acute pediatric vasculitis of unknown etiology and the leading cause of acquired heart disease in children in the United States.

Recent years have seen an increase in the development of functional Jiaosu products, including eco-friendly Jiaosu and antimicrobial healthcare fermentation products. As a result, research on the antibacterial activity of Jiaosu has attracted attention. In the present study, the endophytic yeast WCF016, which exhibits antibacterial activity against Escherichia coli and Staphylococcus aureus, was isolated from the peel of water chestnut and identified as Candida sake via morphological and phylogenetic analyses based on 26S rDNA D1/D2 region sequencing.

Ladderanes are highly strained hydrocarbons consisting of two or more linearly concatenated cyclobutane rings. Strikingly, ladderane moieties are part of unique fatty acids and fatty alcohols that are exclusively found in the membrane lipids of anaerobic ammonium-oxidizing (anammox) bacteria. These bacteria express a distinctive gene cluster (cluster I) that has been suggested to be responsible for ladderane fatty acid (FA) biosynthesis in addition to a cluster likely involved in canonical FA biosynthesis (cluster III).

Article Synopsis
- Terpenoid cyclases (TCs) are crucial for producing diverse natural compounds, with the BcABA3 enzyme from the fungus Botrytis cinerea representing a unique type that deviates from typical TCs.
- Crystal structures of BcABA3 and related enzymes show they have an all-α-helix fold and interact with specific substrates through a unique binding mechanism.
- Findings suggest significant potential for exploring more uncharacterized terpenoids synthesized by these enzymes, highlighting the need for further research in this area.
