Protein

Translation initiation factor IF-3

Gene

infC

Organism
Thermus thermophilus (strain HB8 / ATCC 27634 / DSM 579)
Status
Reviewed - Annotation score: 3 out of 5- Experimental evidence at protein leveli

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.
