Protein

Glycine--tRNA ligase 1, mitochondrial

Gene

GRS1

Organism
Saccharomyces cerevisiae (strain ATCC 204508 / S288c) (Baker's yeast)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

Catalyzes the attachment of glycine to tRNA(Gly). Is also able produce diadenosine tetraphosphate (Ap4A), a universal pleiotropic signaling molecule needed for cell regulation pathways, by direct condensation of 2 ATPs (By similarity).By similarity1 Publication

Miscellaneous

Present with 98400 molecules/cell in log phase SD medium.1 Publication

Caution

GRS1, which appears to be a duplication of GRS2, is necessary and sufficient for both mitochondrial and cytoplasmic glycyl-tRNA synthetase activities, suggesting that GRS2 may not be essential.Curated

Catalytic activityi

ATP + glycine + tRNA(Gly) = AMP + diphosphate + glycyl-tRNA(Gly).
