Protein

Translation initiation factor IF-2

Gene
infB, Psyc_0069
Organism
Psychrobacter arcticus (strain DSM 17307 / 273-4)
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 By similarity.UniRule annotation
