Conditions are described under which the nonphysiological substrate mercuric bromide (HgBr2) is rapidly turned over, both by the wild type (CCCC) and by an active site double mutant (CCAA) of mercuric reductase in which the C-terminal cysteines 557' and 558'

Mercury was detected in all analysed samples of swordfish, marlin, shark and tuna purchased from major supermarket outlets and fish retailers in three cities across Canada. Total mercury and methylmercury levels ranged up to 3845 and 2346 ng g(-1), respectively.

D-Galactose was converted into the glycosylating agents 4-azido-2,3-di-O-benzyl-4-deoxy-6-O-propionyl-alpha-D-glucopyranosyl chloride (11) and the methyl beta-D-thiopyranoside 19. Condensation of 11 with 2,5-diazido-1,6-di-O-benzoyl-2,5-di-deoxy-L-iditol in the presence of mercury salts gave 24% of 2,5-diazido-3-O-(4-azido-2,3-di-O-benzyl-4-deoxy-6-O-propionyl-alp ha-D- glucopyranosyl)-1,6-di-O-benzoyl-2,5-dideoxy-L-iditol. Methyl trifluoromethanesulfonate-promoted glycosylation of 1,3-diazido-2-O-benzyl-1,3-dideoxy-5,6-O-isopropylidene-D-gulit ol with 19

In Saccharomyces cerevisiae, disruption of the YCF1 gene increases the sensitivity of cell growth to mercury. Transformation of the resulting ycf1 null mutant with a plasmid harbouring YCF1 under the control of the GAL promoter largely restores the wild-type resistance

The oxidation of elemental mercury (Hg0) to the divalent gaseous mercury dibromide (HgBr2) has been proposed to account for the removal of Hg0 during depletion events in the springtime Arctic. The mechanism of this process is explored in this paper
