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 367 374 GTP (By similarity).
 NP_BIND 413 417 GTP (By similarity).
 NP_BIND 467 470 GTP (By similarity).
 REGION 361 509 G-domain.
