'The microbiome is a bit like a forest': How bacteria in the vagina can improve health
The microbiome in the vagina has received less attention than its cousin in the gut – but a well-balanced vaginal microbiome can help protect overall health.

GlcNAc build-up acts as a key metabolic signal in #Streptomyces, but how does it triggers developmental responses? @gillesvanwezel.bsky.social &co show that the enzyme NagS dehydrates GlcNAc-6P into a reactive intermediate, triggering a toxicity-based checkpoint @plosbiology.org 🧪 plos.io/44pE08I
Top: (Top row) Sensitivity of S. coelicolor mutants to GlcNAc. Spores (5 × 105 CFU) of S. coelicolor M145 and its mutant derivatives ∆nagB, SMA11, ∆nagB∆nagS, ∆nagB∆nagSC (∆nagB∆nagS expressing nagS) and ∆nagB∆nagSE (∆nagB∆nagS with empty plasmid pSET152) were streaked on MM agar plates with 1% mannitol (Mann) and 1% mannitol plus 10 mM GlcNAc (GlcNAc). (Bottom row) NagS and its role in GlcNAc sensing. Spores of M145 and ∆nagS were plated on MM and R5 with 0, 0.001, 0.01, 0.1, 1, 5, 10, 20, 50, 100, 150, and 200 mM GlcNAc. Note that nagS mutants hardly respond to GlcNAc. Bottom: Model for the metabolic control of development by GlcNAc and NagS. During late vegetative growth of streptomycetes, the old vegetative or substrate hyphae are degraded in a process of programmed cell death (PCD), to produce the nutrients required to build the aerial mycelium (see mycelial drawings on the right). Mycelial lysis results in breakdown of the cell-wall, leading to the accumulation of GlcNAc-6P, which is a major nutritional signal for the onset of development and antibiotic production. NagS converts GlcNAc-6P into 6P-chromogen I (denoted as X-Ac-6P), which in turn is deacetylated by NagA into a toxic metabolite (denoted as X-6P) that resembles ribose. The toxic metabolite promotes cell lysis, thus releasing more GlcNAc-6P that serves as substrate for NagS and NagA. A salvage pathway then switches off the toxic pathway again. For this, GlcNAc-6P is converted by NagA and NagB into Fructose-6P (Fru-6P), which enters the pentose phosphate pathway (PPP), thereby producing 6-phosphogluconate (6-PG), a metabolic inhibitor of NagS. Thus, production of toxic metabolites ceases and the transition to aerial growth can be initiated. Arrows with round ends represent inhibition, dashed arrow shows proposed activity.

Structures of 3 of the 4 #Ecoli Type VII #ABCtransporter systems are known. @allistercrow.bsky.social &co use #cryoEM structures to show that the 4th, YbbAP, may extract hydrophobic compounds from the inner membrane & present them to periplasmic TesA for hydrolysis @plosbiology.org 🧪 plos.io/49EhNHD
Top left: CryoEM map for the ATP-bound YbbAP at 3.6 Å resolution, and (below)ATP-bound YbbAP-TesA complex contoured to visualize the detergent belt. Maps are shown at two contour levels—a partially transparent low contour map is shown in white (4.5 σ), and a high contour map is shown colored by nearest protein chain (7 σ). Top right: Structures of apo YbbAP, ATP analogue-bound YbbAP, and ATP analogue-bound YbbAP-TesA. Proteins are shown in cartoon representation (YbbA green, YbbP teal, and TesA pink), and the non-hydrolyzable ATP analogue (AMP-PNP) is shown in blue atomic spheres. Bottom: Biological functions of the four Type VII ABC transporters in Escherichia coli. From left to right: YbbAP-TesA forms a novel type VII ABC transporter involved in extraction of hydrophobic compounds from the inner membrane and enzymatic hydrolysis in the periplasm; FtsEX-EnvC uses transmembrane conformational changes to regulate the activity of peptidoglycan amidases in the periplasm; MacAB-TolC drive efflux of antibiotics and small toxins across the outer membrane; and LolCDE extracts lipoproteins from the inner membrane and delivers them to the outer membrane via the LolA shuttle.

Our world is one of impetuous life; once a new niche open, by a volcanic island or (now more often) retreating glaciers, generalist, metabolically flexible, microbial life will rush in to inhabit it and be the base of future succession. 🧪

A hacking cough, muscle aches and full-body fatigue likely indicate a viral infection such as flu or COVID. Even specialists struggle to tell which virus is which from symptoms alone.
