In enzymology, a serine–tRNA ligase (EC 6.1.1.11) is an enzyme that catalyzes the chemical reaction
- ATP + L-serine + tRNASer AMP + diphosphate + L-seryl-tRNASer
The 3 substrates of this enzyme are ATP, L-serine, and tRNASer, whereas its 3 products are AMP, diphosphate, and L-seryl-tRNASer.
This enzyme belongs to the family of ligases, to be specific those forming carbon–oxygen bonds in aminoacyl-tRNA and related compounds. The systematic name of this enzyme class is L-serine:tRNASer ligase (AMP-forming). Other names in common use include seryl-tRNA synthetase, SerRS, seryl-transfer ribonucleate synthetase, seryl-transfer RNA synthetase, seryl-transfer ribonucleic acid synthetase, and serine translase. This enzyme participates in glycine, serine and threonine metabolism, and aminoacyl-tRNA biosynthesis.
