Protein existenceInferred from homology

General annotation (Comments)

Function

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 By similarity. HAMAP-Rule MF_00080

Subunit structure

Monomer By similarity. HAMAP-Rule MF_00080

Subcellular location

Cytoplasm By similarity HAMAP-Rule MF_00080.

Sequence similarities

Belongs to the IF-3 family.

Sequence caution

The sequence AAO29745.1 differs from that shown. Reason: Erroneous initiation.
