Functional differentiation of the catalytic subunits YnfE and YnfF involved in selenate and tellurate reduction in Escherichia coli.

Selenate and tellurate are toxic chalcogen oxyanions that can be reduced by several bacteria to the less-toxic elemental forms of selenium and tellurium. In Escherichia coli, the ynfEFGH gene cluster encodes two complex iron-sulfur molybdoenzymes, Yn…
