GCW_00615

Uniprot: A0A0F6CK10
Description: translation initiation factor IF-2
EC number:
Annotation score: 2 out of 5
Miscellaneous [CC]:
Protein existence: Inferred from homology
Catalytic activity:
Cofactor:
Enzyme regulation:
Function [CC]: FUNCTION: 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. {ECO:0000256|HAMAP-Rule:MF_00100, ECO:0000256|RuleBase:RU000644}.
