In E. coli cells, IF2 (Initiation Factor 2) is responsible for attaching the initiator tRNA to the ribosome, along with GTP. This is the first step in the initiation of protein synthesis. The other options, eIF2, eIF2B, IF3, and eIF5, are factors involved in initiation of protein synthesis in eukaryotic cells, rather than bacterial cells.
