Aminolipids elicit functional trade-offs between competitiveness and bacteriophage attachment in Ruegeria pomeroyi

Rachel Stirrup et al.

Summary: Lipids play a crucial role in maintaining cell integrity and homeostasis. The cosmopolitan marine roseobacter clade (MRC) and SAR11 clade bacteria produce a variety of amino acid-containing lipids. The study reveals that these lipids are present in both the inner and outer membranes of MRC bacteria. The inability to produce these lipids impacts membrane proteome, nutrient transport, competitiveness, and phage attachment.

A novel class of sulfur-containing aminolipids widespread in marine roseobacters

Alastair F. Smith et al.

Summary: Marine roseobacter group bacteria are important players in ocean ecosystems, capable of adjusting their membrane lipid composition in response to environmental changes. A novel sulfur-containing aminolipid (SAL) was identified, which plays a key role in biofilm formation in roseobacters. The gene salA encoding a lyso-lipid acyltransferase essential for SAL biosynthesis is widely distributed and actively expressed in Tara Oceans metagenomes and metatranscriptomes.

ExoS/ChvI Two-Component Signal-Transduction System Activated in the Absence of Bacterial Phosphatidylcholine

Otto Geiger et al.

Summary: The lack of phosphatidylcholine (PC) in Sinorhizobium meliloti membrane activates the ExoS/ChvI two-component regulatory system, leading to transcriptional and protein level changes that affect bacterial motility and succinoglycan biosynthesis.
