Iron and iron-containing compounds are essential for bacterial virulence and host infection. Hemin is an important supplement compound for bacterial survival in an iron-deficient environment. Despite strong interest in hemin metabolism, the detailed mechanism of hemin transportation in Gram-positive bacteria is yet to be reported. The results of our study revealed that the homologous proteins of SPD_0310 were significantly conservative in Gram-positive bacteria (<i>P < </i>0.001), and these prot ...[more]

A Bifunctional SPD-0090 contributes virulence of Streptococcus pneumoniae by affecting iron transport and galactose metabolism

Project description:Streptococcus pneumoniae (S.pneumoniae) is a Gram-positive bacterial pathogen that colonizes on the mucosal surfaces of the host's nasopharynx and upper respiratory tract and results in pneumonia. In order to survive and infect the host, S.pneumoniae must have obtain essential nutrients, such as transition metal ions . Our previous study had shown that the mRNA and protein levels of SPD-0090 are significantly upregulated in the ΔpiuA/ΔpiaA/ΔpitA triple mutant (three major iron transports), but its detailed biological function is unknown. In this study, we found that the knockout spd-0090 gene induced a delayed growth in the medium with different sugar sources. F urther iTRAQ quantitative proteomics studies revealed that SPD-0090 affects galactose metabolism and iron ion transport system. Then RT-qPCR and intracellular galactose content assays showed that SPD-0090 affects galactose uptake, leads to reduced galactose utilization. In addition, in vitro biochemical assays showed that SPD-0090 is a hemin transporter and affects iron uptake. Notably the knockout of spd-0090 resulted in an enhanced infection ability of S.pneumonaie to Our study reveals that the dual function of SPD-0090 plays an important role in the virulence of S.pneumoniae.

Proteomic investigation into the action mechanism of inhibitor ptsc1 against Streptococcus pneumoniae

Project description:Phenyl-thiazolylurea-sulfonamides compound 1 (ptsc1) is a new and efficient bacterial inhibitor. Although the inhibitor has antibacterial activity against several model bacteria, the details of its mechanism in Streptococcus pneumoniae (S. pneumoniae) have not been revealed. In the current study, we found that ptsc1 can significantly inhibit the growth of S. pneumoniae. To further investigate the molecular mechanism of its antibacterial effects, quantitative proteomics was performed to identify differential expressed proteins in S. pneumoniae. Compared with the normal group, the expression levels of 38 proteins were upregulated, whereas those of 88 proteins were downregulated (> 1.3 fold-change) in the experimental group (P < 0.05). KEGG pathways analysis revealed that ptsc1 regulated proteins were mainly involved in carbohydrate metabolism, DNA replication and repair, pyrimidine metabolism, fatty acid biosynthesis and oxidative phosphorylation pathways. The results of GO enrichment analysis showed that the inhibitor could lead to dysregulation of bacterial translation and energy metabolism, and cause intracellular oxidative stress.

Dirhodium (II) Complex Interferes with Iron-Transport System to Exert Antibacterial Action against Streptococcus pneumoniae

Project description:Drug resistance in bacteria is becoming a significant threat to global public health, and the development of novel and efficient antibacterial compounds is urgently needed. Recently, rhodium complexes have attracted attention as antimicrobial agents, yet their antibacterial mechanism remains unknown. In this study, we observed that the dirhodium (II) complex Rh2Ac4 inhibited Streptococcus. pneumoniae growth without significant cytotoxic side-effects on host cells in vitro. We subsequently investigated the antibacterial mechanism of Rh2Ac4 using iTRAQ-based proteomics combined with cellular and biochemical assays. Bioinformatics analysis on the proteomic alterations demonstrated that six molecular functional groups, including metal ion binding and twelve metabolic pathways, were significantly affected after treatment with Rh2Ac4. The interaction network analysis of metal ion binding proteins suggested that Rh2Ac4 decreased the protein expression levels of SPD_1652, SPD_1590 and Gap, which are associated with haem uptake/metabolism. Cellular and biochemical assays further confirmed that Rh2Ac4 could be taken up by bacteria via the PiuABCD haem-uptake system. The structurally similar Rh complex may compete with Fe-haem to decrease Fe-uptake via the PiuABCD system, disrupting iron metabolism to exert its antibacterial activity against S. pneumoniae. These data indicate that Rh2Ac4 is a promising new drug for the treatment of S. pneumoniae infections.

Klebsiella pneumoniae peptide hijacks a Streptococcus pneumoniae permease to subvert pneumococcal growth and colonization

Project description:Treatment of pneumococcal infections is limited by antibiotic resistance and exacerbation of disease by bacterial lysis releasing pneumolysin toxin and other inflammatory factors. We identified a novel peptide in the Klebsiella pneumoniae secretome, which enters Streptococcus pneumoniae via its AmiA-AliA/AliB permease. Subsequent downregulation of genes for amino acid biosynthesis and peptide uptake was associated with reduction of pneumococcal growth in defined medium and human cerebrospinal fluid, irregular cell shape, decreased chain length and decreased genetic transformation. The bacteriostatic effect was specific to S. pneumoniae and Streptococcus pseudopneumoniae with no effect on Streptococcus mitis, Haemophilus influenzae, Staphylococcus aureus or K. pneumoniae. Peptide sequence and length were crucial to growth suppression. The peptide reduced pneumococcal adherence to primary human airway epithelial cell cultures and colonization of rat nasopharynx, without toxicity. We also analysed the effect of peptide on the proteome of S. pneumoniae. We found alteration of the proteome by the peptide with some proteins turned on or off in line with the transcriptomic changes. We therefore identified a peptide with potential as a therapeutic for pneumococcal diseases suppressing growth of multiple clinical isolates, including antibiotic resistant strains, while avoiding bacterial lysis and dysbiosis.

Lung gene expression analysis of WT, Nlrp3-, Asc-deficient mice in Streptococcus pneumoniae D39 and ATCC6303 infection

Project description:Streptococcus (S.) pneumoniae is the most frequently isolated causative pathogen community-acquired pneumonia, a leading cause of mortality worldwide. We investigated the role of the inflammasome sensor NLRP3 and the inflammasome adapter ASC during S. pneumoniae pneumonia. Detailed analysis of the early inflammatory response in the lung by whole genome transcriptional profiling, we identified several mediators that were differentially expressed between Nlrp3-/- and Asc-/ - mice. WT, Nlrp3- and Asc-deficient mice were intranasally inocculated with Streptococcus pneumoniae D39 and ATCC6303 both at high and low dose. Lung homogenates were harvested and gene expression profiling was performed.
