Genome Sequence of Lactiplantibacillus plantarum ATCC 202195, a Probiotic Strain That Reduces Sepsis and Other Infections during Early Infancy.

The draft genome of probiotic ATCC 202195, with the trademark PPLP-217, is comprised of 3,368,305 bp with a G+C content of 44.3% and no plasmids. The strain is able to grow on lactose, raffinose, and fructooligosaccharides.

Draft Genome Sequence of the Caffeine-Degrading Methylotroph Pinkel.

A pink-pigmented facultative methylotroph, Pinkel, was isolated from compost by selective enrichment with caffeine (3,5,7-trimethylxanthine) as the sole carbon, nitrogen, and energy source. We report here its high-quality draft genome sequence, assembled in 35 contigs totaling 5,630,907 bp. We identified 5,681 protein-coding sequences, including those putatively involved in caffeine degradation.

High-Amylose Maize, Potato, and Butyrylated Starch Modulate Large Intestinal Fermentation, Microbial Composition, and Oncogenic miRNA Expression in Rats Fed A High-Protein Meat Diet.

High red meat intake is associated with the risk of colorectal cancer (CRC), whereas dietary fibers, such as resistant starch (RS) seemed to protect against CRC. The aim of this study was to determine whether high-amylose potato starch (HAPS), high-amylose maize starch (HAMS), and butyrylated high-amylose maize starch (HAMSB)-produced by an organocatalytic route-could oppose the negative effects of a high-protein meat diet (HPM), in terms of fermentation pattern, cecal microbial composition, and colonic biomarkers of CRC. Rats were fed a HPM diet or an HPM diet where 10% of the maize starch was substituted with either HAPS, HAMS, or HAMSB, for 4 weeks.

Discovery and Characterization of a Peptoid with Antifungal Activity against .

Studies show there is an increasing rate of fungal infections, especially in immunocompromised patients and treatments for fungal genera, such as , , and , carry significant cytotoxicity with an increasing prevalence of antifungal resistance. We have previously reported a high-throughput assay for identifying peptoids with antimicrobial properties from combinatorial libraries. Here we report the application of this assay in identifying a peptoid with antifungal properties against .

Synthesis of cyclocaric acid A and comparison to material from Cyclocarya paliurus.

Components previously reported from Cyclocarya paliurus include the oleananes cyclocaric acids A and B, with cyclocaric acid A possessing an oxetane ring. Isolation of cyclocaric acid A from the plant extract and comparison to the literature report show that the compound originally reported as cyclocaric acid A is, in fact, hederagenin. This was confirmed by independent synthesis of the oxetane and indicates that cyclocaric acid A may not actually be a natural product.

Regulation of Yersinia protein kinase A (YpkA) kinase activity by multisite autophosphorylation and identification of an N-terminal substrate-binding domain in YpkA.

The serine/threonine protein kinase YpkA is an essential virulence factor produced by pathogenic Yersinia species. YpkA is delivered into host mammalian cells via a type III secretion system and localizes to the inner side of the plasma membrane. We have previously shown that YpkA binds to and phosphorylates the α subunit of the heterotrimeric G protein complex, Gαq, resulting in inhibition of Gαq signaling.

A HIF1alpha regulatory loop links hypoxia and mitochondrial signals in pheochromocytomas.

Pheochromocytomas are neural crest-derived tumors that arise from inherited or sporadic mutations in at least six independent genes. The proteins encoded by these multiple genes regulate distinct functions. We show here a functional link between tumors with VHL mutations and those with disruption of the genes encoding for succinate dehydrogenase (SDH) subunits B (SDHB) and D (SDHD).
