In studies using an avidin-binding assay to measure the serum or plasma concentration of biotin, biotin is sometimes assumed to… Expand

Clones of the Escherichia coli bisC locus have been isolated by complementing a bisC mutant for growth with d-biotin d-sulfoxide… Expand

During anaerobic growth, Escherichia coli can reduce phosphomolybdate. The reduction can also be carried out by washed cells… Expand

The bisC gene of Escherichia coli is tentatively identified as the structural gene for biotin sulfoxide reductase by the… Expand
