Two genes homologous to lpxL and lpxM from Escherichia coli and other gram-negative bacteria, which are involved in lipid A acyloxyacylation, were identified in Neisseria meningitidis strain H44/76 and insertionally inactivated. Analysis by tandem mass spectrometry showed that one of the resulting mutants, termed lpxL1, makes lipopolysaccharide (LPS) with penta- instead of hexa-acylated lipid A...

Here, we present the draft genome sequence of Thermus filiformis strain ATCC 43280, a thermophile bacterium capable of producing glycosylated carotenoids acylated with branched fatty acids and enzymes of biotechnological potential.

Abstract Toll-like receptor 4 (TLR4) is a canonical innate immune for the Gram-negative bacterial outer membrane component lipopolysaccharide (LPS). TLR4 deficiency has been shown to contribute UV-induced carcinogenesis in epidermal cells. cellular damage results apoptosis which characterized by non-inflammatory cell death through cleavage and activation of caspase-3. Utilizing enzyme combinati...

background: resistin and ghrelin are hormones that have roles in the glucose and lipid homeostasis and weight regulation. human studies regarding resistin and ghrelin in diabetic patients are scarce, especially in the cases of normotensive and non-obese patients. this study was designed to illuminate some of the missing points.methods: eighty diabetic patients and eighty healthy individuals par...

Anthocyanins are natural pigments that could be involved in various health effects. Red oranges are an important dietary source of anthocyanins, including cyanidin 3-glucoside (Cy 3-glc) and an acylated derivative, cyanidin 3-(6''-malonyl)-glucoside (Cy 3-malglc). The aim of this study was to evaluate the absorption and metabolism of red orange anthocyanins in rats fed an anthocyanin-enriched d...
