Organism

Xylella fastidiosa (strain Temecula1 / ATCC 700964) [Complete proteome] [HAMAP]

Taxonomic identifier

183190 [NCBI]

Taxonomic lineage

cellular organisms › Bacteria › Proteobacteria › Gammaproteobacteria › Xanthomonadales › Xanthomonadaceae › Xylella › Xylella fastidiosa

Protein attributes

Sequence length	180 AA.
Sequence status	Complete.
Protein existence	Inferred 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.
Subcellular location	Cytoplasm By similarity.
Sequence similarities	Belongs to the IF-3 family.
Sequence caution	The sequence AAO29745.1 differs from that shown. Reason: Erroneous initiation.
