Journal Article
Osman, D., Martini, M. A., Foster, A. W., Chen, J., Scott, A. J., Morton, R. J., …Robinson, N. J. (2019). Bacterial sensors define intracellular free energies for correct enzyme metalation. Nature Chemical Biology, 15(3), 241-249. https://doi.org/10.1038/s41589-018-0211-4

There is a challenge for metalloenzymes to acquire their correct metals because some inorganic elements form more stable complexes with proteins than do others. These preferences can be overcome provided some metals are more available than others. Ho... Read More about Bacterial sensors define intracellular free energies for correct enzyme metalation.

A tight tunable range for Ni(II) sensing and buffering in cells (2017)
Journal Article
Foster, A., Pernil, R., Patterson, C., Scott, A., Pålsson, L., Pal, R., …Robinson, N. (2017). A tight tunable range for Ni(II) sensing and buffering in cells. Nature Chemical Biology, 13(4), 409-414. https://doi.org/10.1038/nchembio.2310

The metal affinities of metal-sensing transcriptional regulators co-vary with cellular metal concentrations over more than 12 orders of magnitude. To understand the cause of this relationship, we determined the structure of the Ni(II) sensor InrS and... Read More about A tight tunable range for Ni(II) sensing and buffering in cells.

The Effectors and Sensory Sites of Formaldehyde-Responsive Regulator FrmR and Metal-Sensing Variant (2016)
Journal Article
Osman, D., Piergentili, C., Chen, J., Sayer, L., Usón, I., Huggins, T., …Pohl, E. (2016). The Effectors and Sensory Sites of Formaldehyde-Responsive Regulator FrmR and Metal-Sensing Variant. Journal of Biological Chemistry, 291(37), 19502-19516. https://doi.org/10.1074/jbc.m116.745174

The DUF156 family of DNA-binding, transcriptional-regulators include metal-sensors which respond to cobalt and/or nickel (RcnR, InrS) or copper (CsoR), plus CstR which responds to persulfide, and formaldehyde-responsive FrmR. Unexpectedly, the allost... Read More about The Effectors and Sensory Sites of Formaldehyde-Responsive Regulator FrmR and Metal-Sensing Variant.

A cytosolic Ni(II) sensor in cyanobacterium: Nickel-detection follows nickel-affinity across four families of metal-sensors (2012)
Journal Article
Foster, A., Patterson, C., Pernil, R., Hess, C., & Robinson, N. (2012). A cytosolic Ni(II) sensor in cyanobacterium: Nickel-detection follows nickel-affinity across four families of metal-sensors. Journal of Biological Chemistry, 287(15), 12142-12151. https://doi.org/10.1074/jbc.m111.338301

Efflux of surplus Ni(II) across the outer and inner membranes of Synechocystis PCC 6803 is mediated by the Nrs system under the control of a sensor of periplasmic Ni(II), NrsS. Here, we show that the product of ORF sll0176, which encodes a CsoR/RcnR-...
