Functional Description
 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). 
Sequence Annotation
 NP_BIND 80 87 GTP (By similarity).
 NP_BIND 126 130 GTP (By similarity).
 NP_BIND 180 183 GTP (By similarity).
 REGION 74 222 G-domain.
