Methionine Sulfoxide Reductases Contribute to Anaerobic Fermentative Metabolism in <i>Bacillus cereus</i>.

Antioxidants (Basel, Switzerland) 20210520 5

Reversible oxidation of methionine to methionine sulfoxide (Met(O)) is a common posttranslational modification occurring on proteins in all organisms under oxic conditions. Protein-bound Met(O) is reduced by methionine sulfoxide reductases, which thus play a significant antioxidant role. The facultative anaerobe <i>Bacillus cereus</i> produces two methionine sulfoxide reductases: MsrA and MsrAB. MsrAB has been shown to play a crucial physiological role under oxic conditions, but little is known ...[more]

Mycobacterium smegmatis secreting methionine sulfoxide reductase A (MsrA) modulates cellular processes in mouse macrophages

Project description:Methionine sulfoxide reductase A (MsrA) is an antioxidant repair enzyme that reduces the oxidized methionine (Met-O) in proteins to methionine (Met). It plays a pivotal role in the cellular processes has been well established by overexpressing, silencing and knocking down of MsrA or by deleting the gene encoding MsrA in several species. We are specifically interested in understanding the role of secreted MsrA of bacterial pathogens. To elucidate this, we infected mouse bone marrow derived macrophages (BMDMs) with recombinant Mycobacterium smegmatis strain (MSM) secreting a bacterial MsrA or M. smegmatis strain (MSC) carrying only the control vector. BMDMs infected with MSM induced higher levels of ROS and TNF-α than BMDMs infected with MSC. The increased ROS and TNF-α in BMDMs infected with MSM correlated with elevated necrotic cell death. Further, RNA-Seq transcriptome analysis of BMDMs infected with MSC and MSM revealed differential expression of protein and RNA coding genes, suggesting that bacterial delivered MsrA could modulate the host cellular processes. Finally, KEGG pathway enrichment analysis identified down-regulation of cancer related signaling genes in MSM infected cells, indicating that MsrA has the potential to regulate the development and progression of cancer.

Next Generation Sequencing of Wild Type and Mice Knocked Out for Known Methionine Sulfoxide Reducatases

Project description:Methionine sulfoxide reductase (Msr) is an important antioxidant enzyme. The mammalian Msr family has four members: MsrA, MsrB1, MsrB2, and MsrB3. We generated a mouse strain with deletion of all four Msr proteins. Deletion was confirmed by Western blotting. The quadruple knockout mouse is viable, and growth, development, and fertility appear normal. However, they are unexpectedly resistanct to oxidative stresses. We therefore determined the RNA expression profile in liver and heart of wild-type and quadruple knockout mice.

The fused methionine sulfoxide reductase MsrAB promotes oxidative stress defense and bacterial virulence in Fusobacterium nucleatum

Project description:Recognizably associated with oral infections, adverse pregnancy outcomes, and colorectal cancer, the Gram-negative oral bacterium Fusobacterium nucleatum is known to colonize many extraoral sites including placenta and colon. How this anaerobe copes with oxidative stress imposed by the host immune response in various tissues is unknown. Here, we revealed that F. nucleatum harbors a gene locus coding for a single, fused methionine sulfoxide reductase (MsrAB), a two-component transduction system (ModRS), thioredoxin (Trx)- and cytochrome c (CcdA)-like proteins. Considering their role in oxidative stress responses, we demonstrated that these genes were increasingly expressed when fusobacterial cells were exposed to hydrogen peroxide. Comparative transcriptome analysis of the parental and modR mutant strains revealed that the response regulator ModR regulates a large regulon including trx, ccdA, and many metabolic genes. Significantly, mutants lacking individual genes within the msrAB locus, including msrAB, were sensitive to reactive oxygen species and defective in adherence/invasion of colorectal epithelial cells, as compared to the parental strain. The msrAB mutant was also defective in survival in macrophage, unlike the rescued and parental strains. Strikingly, in an experimental model of preterm birth this mutant was severely attenuated in virulence, for it failed to colonize the placenta and spread to the amniotic fluid. The results support that the MsrAB system represents a major pathway that protects fusobacteria against oxidative damage and confers virulence and that MsrAB-mediated oxidative stress defense is subjected to regulation by the two-component transduction system ModRS.
