Ferrioxamine B

Ferrioxamine B is a bacterial desferrioxamine siderophore produced by actinomycetes. Ferrioxamine B acts as a ligand for FpvB and FoxA, and is transported into Pseudomonas aeruginosa via the FpvB and FoxA transporters. Ferrioxamine B competitively binds to FpvB, thereby antagonizing the uptake of thiostrepton into Pseudomonas aeruginosa. Ferrioxamine B can provide an iron source to support the growth of Pseudomonas aeruginosa under iron-limiting conditions.

Ferrioxamine B-Fe³⁺ (1 hour) binds FpvB in P. aeruginosa PA14 ΔfpvA ΔfpvB mutant with two distinct sites (K_d1 = 100 ng/mL, K_d2 = 270,000 ng/mL) and is taken up via a proton motive force-dependent mechanism^[1].
Ferrioxamine B (0.0-10 μg/mL) competes with thiostrepton (0.0-17 μg/mL) for binding to FpvB in P. aeruginosa PA14 ΔfpvA ΔfpvB mutant, reducing Thiostrepton (HY-B0990) susceptibility^[1].

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
