GCW_03145

Uniprot: A0A0F6CL42
Description: GTP-binding protein LepA
EC number: 3.6.5.n1
Annotation score: 2 out of 5
Miscellaneous [CC]:
Protein existence: Inferred from homology
Catalytic activity: CATALYTIC ACTIVITY: GTP + H(2)O = GDP + phosphate. {ECO:0000256|HAMAP-Rule:MF_00071}.
Cofactor:
Enzyme regulation:
Function [CC]: FUNCTION: Required for accurate and efficient protein synthesis under certain stress conditions. May act as a fidelity factor of the translation reaction, by catalyzing a one-codon backward translocation of tRNAs on improperly translocated ribosomes. Back-translocation proceeds from a post-translocation (POST) complex to a pre-translocation (PRE) complex, thus giving elongation factor G a second chance to translocate the tRNAs correctly. Binds to ribosomes in a GTP-dependent manner. {ECO:0000256|HAMAP-Rule:MF_00071}.
