Involvement of major facilitator superfamily proteins SfaA and SbnD in staphyloferrin secretion in Staphylococcus aureus.

Abstract excerpt

A paucity of information exists concerning the mechanism(s) by which bacteria secrete siderophores into the extracellular compartment. We investigated the role of SfaA and SbnD, two major facilitator superfamily (MFS)-type efflux proteins, in the secretion of the Staphylococcus aureus siderophores staphyloferrin A (SA) and staphyloferrin B (SB), respectively. Deletion of sfaA resulted in a drastic reduction of SA...
