Assimilatory sulfur metabolism in marine microorganisms
… assimilation of sulfate into cellular organic sulfur compounds was studied in aerobic marine bacteria, with emphasis on the relationship between sulfur metabolism and protein synthesis. The goal of the study was to develop and apply a method for the quantitative assay of total bacterial protein …

Microbial pathways of sulfur metabolism and colorectal cancer risk
… bacteria metabolize organic and inorganic sulfur in order to produce H2S. We observed that microbes that metabolize organic sulfur distinguished AA CRC from NHW CRC subjects and AA controls. We hypothesize that SRB, (inorganic sulfur metabolizers), may impart beneficial functions, such as …

On Sulfur Sensing in Saccharomyces cerevisiae
The unique chemistry available to sulfur compared to oxygen, such as the ability to exist in numerous oxidation states and greater nucleophilicity, makes many of the biochemical reactions requisite for cellular life possible. As a result of this critical importance, organisms have developed several …

Investigation of O-acetylserine sulfhydrylase enzymes from bacterial pathogens as potential drug targets
… pathway, rendering them reliant on alternative sulfur acquisition mechanisms. A key enzyme in the de novo biosynthesis of L-cysteine, O-acetylserine sulfhydrylase (CysK), represents a promising target for antimicrobial intervention due to its essential role in sulfur metabolism and bacterial …

Structural characterization of glycyl radical enzymes in the human gut microbiome
… structural analysis of one GRE involved in sulfur metabolism, structural and biochemical analysis of another GRE involved in nucleotide metabolism, and efforts towards structural characterization of a GRE-AE. C-S bond cleavage of isethionate by the GRE isethionate sulfite-lyase (IslA) …

Interactions of cadmium, zinc, and phosphorus in marine Synechococcus : field uptake, physiological and proteomic studies
… of many proteins involved in carbon and sulfur metabolism suggesting a great metabolic impact. During stationary phase, chronic Cd exposure in this coastal isolate causes an increase in relative chlorophyll a fluorescence and faster mortality rates. The interactions of acute Cd exposure …

The impact of a single nucleotide polymorphism in fusA1 on biofilm formation and virulence in Pseudomonas aeruginosa
… motility, exoenzyme production, quorum sensing, metabolism, synthesis of biofilm-associated proteins and exopolysaccharide production. Most notably was the up-regulation of a major virulence determinant, the type three secretion system, typically characteristic of cells comprising an acute …

Genes involved in thiol release from cysteine and glutathione conjugates by Saccharomyces cerevisiae during wine fermentation
… that it plays a biological role in yeast sulfur metabolism. Moreover, yeast selected for growth on L-cysteine showed improved 4MMP production. However, the uptake of C-4MMP does not occur via the known cysteine permeases, but it is controlled by the nitrogen catabolism repression. The …

INVESTIGATION OF UNIQUE COENZYME A BIOSYNTHETIC AND REDOX FUNCTIONS IN Bacillus anthracis
… of CoAD and is implicated in to function in sulfur metabolism. In order to test the physiological contributions of BACoADR and CoADR-RHD in thiol-disulfide redox homeostasis, as well as germination and outgrowth of the B. anthracis endospore, in-frame deletion mutants of their respective …

Longitudinal gene networks, canonical pathways and functional analysis of microarray data from Longissimus thoracis et lumborum muscle samples of early-weaned Angus steers
… days. Pentose and glucuronate interconversions, Sulfur Metabolism, Steroid biosynthesis and PPAR Signaling Pathway were the most recurrent KEGG significant pathways for this microarray analysis. KEGG pathway results were in accordance with the metabolic processes that were expected to happen …

Clarification of the xanthan biosynthesis mechanism in Xanthomonas campestris pv. campestris B100 by mass spectrometry-based proteome analysis
… quantity of most proteins related to nitrogen metabolism, except for Gdh and GlnA. The levels of proteins involved in sugar nucleotide metabolism remained constant throughout all stages of growth. Except for GumD, GumB, and GumC, the gum proteins exhibited no notable variations during the …

Microbial nitrogen-cycling and cooperation in the terrestrial subsurface
… has the capacity for versatile autotrophic sulfur and anaerobic nitrogen metabolism, including dissimilatory nitrate reduction to ammonium and complete denitrification coupled to sulfur oxidation. As the phylum comprises considerable uncharacterised diversity, the newly-recovered genome was …

Influence of nutrition on the muscle transcriptome and ruminal microbiome in cattle
… the effects of increasing dietary fat and sulfur from (CDS) on the ruminal microbiome. Alpha-diversity and species richness decreased (linear; P < 0.05) in the liquid fraction for steers fed greater CDS. At the phyla level, relative abundance of Bacteroidetes decreased in steers fed …

Quantitative Trait Loci (Qtl) Analysis Of Sulfur Sensitivity In Vitis Aestivalis-Derived 'Norton'
<p>The grape and wine industry relies heavily on sulfur and sulfur containing compounds to control the fungal disease powdery mildew (PM). Sulfur dioxide induces large-scale transcriptomic modification in the Eurasian grape species Vitis vinifera with little to no phytotoxicity. However, genetic …
