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].
Large ribosomal subunit protein uL24, C-terminal domain
This entry describes the C-terminal domain in large ribosomal subunit protein uL24 (also known as RPL26). RPL26 is one of the proteins from the large ribosomal subunit. In their mature form, these proteins have 103 to 150 amino-acid residues. RPL26 m ...
This entry describes the C-terminal domain in large ribosomal subunit protein uL24 (also known as RPL26). RPL26 is one of the proteins from the large ribosomal subunit. In their mature form, these proteins have 103 to 150 amino-acid residues. RPL26 makes very minor contributions to the biogenesis structure, and function of 60s ribosomal subunits [1]. However, RPL24 is essential to generate the first intermediate during 50s ribosomal subunits assembly [2]. RPL26 have an extra-ribosomal function to enhances p53 translation after DNA damage [3].
Ribosomal protein L25 is an RNA binding protein, that binds 5S rRNA. This family includes Ctc from B. subtilis Swiss:P14194, which is induced by stress.
