A Simple Spectrophotometric Streptavidin-Biotin Binding Assay Utilizing Biotin-4-Fluorescein., Mark Waner, David Mascotti
Mark J. Waner
A new assay for biotin binding capacity of Streptavidin (SA) is presented in this work. The assay is based on the large decrease in the extinction coefficient at 493 nm that accompanies binding of biotin-4-fluorescein (B4F) to SA. This decrease is attributed to formation of a charge transfer complex between the B4F-donor and one or more SA residues. We show that one may observe the stoichiometric binding via monitoring the absorbance at 493 nm using either SA or B4F as the titrant. The sensitivity of the assay is at the lower end of similar fluorimetric and photometric assays. Though the …

As in other P-type ATPases, metal binding to transmembrane metal-binding sites (TM-MBS) in Cu(+)-ATPases is required for enzyme phosphorylation and subsequent transport. However, Cu(+) does not access Cu(+)-ATPases in a free (hydrated) form but is bound to a chaperone protein. Cu(+) transfer from Cu(+) chaperones to regulatory cytoplasmic metal-binding domains (MBDs) present in these ATPases has been described, but there is no evidence of a proposed subsequent Cu(+) movement from the MBDs to the TM-MBS. Alternatively, we postulate the parsimonious Cu(+) transfer by the chaperone directly to TM-MBS. Testing both models, the delivery of Cu(+) by Archaeoglobus fulgidus Cu(+) chaperone …
