Protein

Serine--tRNA ligase

Gene
serS, SynRCC307_0547
Organism
Synechococcus sp. (strain RCC307)
Status
Reviewed - Annotation score: 3 out of 5 - Protein inferred from homologyi

Functioni

Catalyzes the attachment of serine to tRNA(Ser). Is also able to aminoacylate tRNA(Sec) with serine, to form the misacylated tRNA L-seryl-tRNA(Sec), which will be further converted into selenocysteinyl-tRNA(Sec) By similarity.UniRule annotation

Catalytic activityi

ATP + L-serine + tRNA(Ser) = AMP + diphosphate + L-seryl-tRNA(Ser).UniRule annotation
ATP + L-serine + tRNA(Sec) = AMP + diphosphate + L-seryl-tRNA(Sec).UniRule annotation
