Prokaryotic initiation factor-2 : ウィキペディア英語版 | Prokaryotic initiation factor-2 Prokaryotic initiation factor-2 is a prokaryotic initiation factor. IF2 binds to an initiator tRNA and controls the entry of that tRNA into the ribosome. IF2, bound to GTP, binds to the 30S P site. After associating with the 30S subunit, fMet-tRNAf binds to the IF2 then IF2 transfers the tRNA into the partial P site. When the 50S subunit joins, it hydrolyzes GTP to GDP and Pi, causing a conformational change in the IF2 that causes IF2 to release and allow the 70S subunit to form. ==References==
