A, B [auth F]	ARO:3003733	fusC	FusC is a fusidic acid resistance gene enabling ribosomal translocase EF-G dissociation from the ribosome that has been detected in Staphylococcus aureus and Staphylococcus intermedius. Its mechanism is believed to be similar to fusB due to its high level of sequence homology. It is considered a FusB-type protein.	CARD (4.0.0)

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].	Domain

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].	Domain
