UniProtKB - Q6F1S8 (IF3_MESFL)
Protein
Translation initiation factor IF-3
Gene
infC
Organism
Mesoplasma florum (strain ATCC 33453 / NBRC 100688 / NCTC 11704 / L1) (Acholeplasma florum)
Status
Functioni
IF-3 binds to the 30S ribosomal subunit and shifts the equilibrum between 70S ribosomes and their 50S and 30S subunits in favor of the free subunits, thus enhancing the availability of 30S subunits on which protein synthesis initiation begins.
