Metalloproteins and metal sensing

KJ Waldron, JC Rutherford, D Ford, NJ Robinson - Nature, 2009 - nature.com
Almost half of all enzymes must associate with a particular metal to function. An ambition is
to understand why each metal–protein partnership arose and how it is maintained. Metal …

Overcoming universal restrictions on metal selectivity by protein design

TS Choi, FA Tezcan - Nature, 2022 - nature.com
Selective metal coordination is central to the functions of metalloproteins:, each
metalloprotein must pair with its cognate metallocofactor to fulfil its biological role. However …

Metal preferences and metallation

AW Foster, D Osman, NJ Robinson - Journal of biological chemistry, 2014 - ASBMB
The metal binding preferences of most metalloproteins do not match their metal
requirements. Thus, metallation of an estimated 30% of metalloenzymes is aided by metal …

Transition metals in control of gene expression

TV O'Halloran - Science, 1993 - science.org
Metalloproteins play structural and catalytic roles in gene expression. The metalloregulatory
proteins are a subclass that exerts metal-responsive control of genes involved in respiration …

Metal sensor proteins: nature's metalloregulated allosteric switches

DP Giedroc, AI Arunkumar - Dalton Transactions, 2007 - pubs.rsc.org
Metalloregulatory proteins control the expression of genes that allow organisms to quickly
adapt to chronic toxicity or deprivation of both biologically essential metal ions and heavy …

Bacterial sensors define intracellular free energies for correct enzyme metalation

D Osman, MA Martini, AW Foster, J Chen… - Nature chemical …, 2019 - nature.com
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 …

Femtomolar sensitivity of metalloregulatory proteins controlling zinc homeostasis

CE Outten, TV O'Halloran - Science, 2001 - science.org
Intracellular zinc is thought to be available in a cytosolic pool of free or loosely bound Zn (II)
ions in the micromolar to picomolar range. To test this, we determined the mechanism of zinc …

How do bacterial cells ensure that metalloproteins get the correct metal?

KJ Waldron, NJ Robinson - Nature Reviews Microbiology, 2009 - nature.com
Protein metal-coordination sites are richly varied and exquisitely attuned to their inorganic
partners, yet many metalloproteins still select the wrong metals when presented with …

Affinity gradients drive copper to cellular destinations

L Banci, I Bertini, S Ciofi-Baffoni, T Kozyreva, K Zovo… - Nature, 2010 - nature.com
Copper is an essential trace element for eukaryotes and most prokaryotes. However,
intracellular free copper must be strictly limited because of its toxic side effects. Complex …

Transition metal speciation in the cell: insights from the chemistry of metal ion receptors

LA Finney, TV O'Halloran - Science, 2003 - science.org
The essential transition metal ions are avidly accumulated by cells, yet they have two faces:
They are put to use as required cofactors, but they also can catalyze cytotoxic reactions …
