Disease relevance of phenylmercury

  • The merG gene product is involved in phenylmercury resistance in Pseudomonas strain K-62 [1].
  • When the merG gene in a compatible plasmid was transformed into the E. coli strain carrying pMU29, the high uptake of and high sensitivity to phenylmercury were almost completely restored to their original levels [1].
  • One recombinant plasmid (pMRA17) inducibly encoded a typical broad-spectrum mercurial resistance, whereas the other recombinant plasmid (pMRB01) constitutively conferred hypersensitivity to phenylmercury in the absence of mercuric reductase activity [2].

High impact information on phenylmercury

  • Between the merA and merD genes, an open reading frame encoding a 212 amino acid polypeptide was identified as the merB gene that determines the enzyme organomercurial lyase that cleaves the C--Hg bond of phenylmercury [3].
  • The interactions of inorganic mercury Hg(II), methylmercury (MeHg(I)), ethylmercury (EtHg(I)), and phenylmercury (PhHg(I)) with DNA have been probed by capillary electrophoresis with on-line electrothermal atomic absorption spectrometric detection (CE-ETAAS) in combination with circular dichroism and Fourier transform infrared spectroscopy [4].
  • Capillary electrophoretic separation of four mercury species (inorganic Hg(2+), methyl-, ethyl-, and phenylmercury) was achieved in less than 8 min with an electrolyte consisting of 150 mM 2-amino-2-methyl-propanol (AMP) at pH 11 [5].
  • Escherichia coli cells bearing pMU29, which carries a deletion of the merG gene, took up significantly more phenylmercury than the bacteria with the intact plasmid pMRA17 [1].
  • Deletion of the merG gene from the broad-spectrum mer operon of pMR26 had no effect on the inorganic mercury resistance phenotype, but rendered the bacterium more sensitive to phenylmercury than its isogenic wild-type strain [1].
