Physiological response of Rhizobium leguminosarum during bacteroid development
… seen between the Mn2+ transporters SitABCD and MntH. Single mutations in sitA or mntH did not cause a symbiotic phenotype whereas the double mutant could not form bacteroids on P. sativum, V. faba or V. hirsuta. Intriguingly, no symbiotic phenotype for the double mutant was observed on P. …

The mechanism by which manganese protects Escherichia coli from hydrogen peroxide
… We showed while manganese transport mutants, mntH, have no growth defect, mntH mutants in strains that cannot scavenge H2O2, Hpx- mntH, failed to grow when cultured aerobically. Thus manganese import is only crucial when cells are stressed with H2O2; cells appear to use iron to metallate …

Identification and Characterization of SitABCD, a Metal Ion Transporter of Salmonella Typhimurium
… MntR. A proton dependent manganese transporter, mntH is also under the control of these regulators. In addition, a RpoS mediated growth phase dependent regulation of the sit operon was observed. The sit locus is induced in the animal after invasion of the intestinal epithelium. We show that a sit …

Yield Curves and Macro Variables Interactions and Predictions
… Based on Multitask learning, we achieved a 1-mnth average yield curves prediction accuracy of 80.2% for all yield maturities and studied markets. Additionally, we found out that increasing the hidden nodes led to overfitting the data, hence, we recommend the use of a simple neural network …

Further characterisation of the envelope stress responses of Salmonella Typhimurium
… positive regulation of the virulence factors MntH and GroEL, GroSL, DnaK and ClpB (the heat shock chaperones). In addition, we show critical requirement of ZraSR for maximal carbon-starvation induced cross-resistance to heat and polymyxin B. The ZraR regulon described here includes functional …

Identification and characterization of a novel class of hydrogen peroxide targets in escherichia coli
… role in metal homeostasis through regulation of MntH and Dps. These proteins work to increase Mn concentrations, while sequestering Fe in the stressed cell, respectively. This process allows Mn to metallate and thereby protect enzymes which would otherwise be vulnerable to damage by H2O2. …
