The role of IF-2 in translation in bacterial cells is to:
◦ stabilize free 30S ribosomal subunits to facilitate binding to mRNA.
◦ bind to initiator tRNA to control its entry into the ribosome assembly.
◦ stabilize free 50S ribosomal subunits to facilitate assembly into mature ribosome.
◦ bind to the A site in the initiation complex to prevent aminoacyl tRNA binding.
◦ bind to the P site in the initiation complex to prevent aminoacyl tRNA binding.
