Protein

Translation initiation factor IF-2

Gene

infB

Organism
Helicobacter pylori (strain P12)
Status
Reviewed - Annotation score: 2 out of 5- Protein inferred from homologyi

Functioni

One of the essential components for the initiation of protein synthesis. Protects formylmethionyl-tRNA from spontaneous hydrolysis and promotes its binding to the 30S ribosomal subunits. Also involved in the hydrolysis of GTP during the formation of the 70S ribosomal complex.UniRule annotation
