FusB encodes a 2-domain zinc-binding protein that binds the ribosomal translocase EF-G, causing it to dissociate from the ribosome. This action increases the ribosomal turnover rate and confers resistance to fusidic acid. This protein is considered a FusB-type protein.

FBP_C is a family from the C terminal end of fibronectin-binding proteins. It forms an extended four-cysteine zinc-finger with a unique structural fold. Fibronectin-binding proteins bind to elongation factor G - EF-G, which is mediated by the zinc-finger binding to the C-terminus of EF-G [1]. FBPs release ribosomes by competing with them for EF-G [2].
This domain can be found in the N terminus of the FusB, FusC, and FusD proteins from Staphylococcus aureus. They are elongation factor G (EF-G) binding proteins that are linked to the fusidic acid (FA) resistance in S. aureus [4,5]. The FusB protei ...
This domain can be found in the N terminus of the FusB, FusC, and FusD proteins from Staphylococcus aureus. They are elongation factor G (EF-G) binding proteins that are linked to the fusidic acid (FA) resistance in S. aureus [4,5]. The FusB proteins are two-domain metalloproteins, and this N-terminal domain forms a four-helical bundle whose helices help to stabilise the conformation of the treble-clef zinc-finger in the C-terminal domain [2]. FA is an antibiotic that binds to EF-G, preventing its release from the ribosome, thus stalling bacterial protein synthesis. The FusB proteins provide FA resistance by preventing formation or facilitating dissociation of the FA-locked EF-G-ribosome complex during elongation and ribosome recycling [3].
