Initiation factors are proteins that enhance the binding affinity of the various translational components.
Types of Initiation factors in E. coli
IF1
IF2
IF3
Role of Initiation factors
IF1 - Stabilizes 30S subunit
IF2 - Binds f-met-tRNA to 30S-mRNA complex ; binds to GTP and stimulates hydrolysis
IF3 - Binds 30S subunit to mRNA ; dissociates monosomes into subunits following termination[1]
