Secondary Information

Protein Function attachment of amino acids to their cognate tRNA species; discriminates with high selectivity among many structurally similar tRNAs and amino acids; responsible for the covalent attachment of serine to its cognate tRNASer
Biochemical Properties a member of class II, an unusual enzyme compared with the other synthetases because of its substrate specificity- SerRS not only serylates tRNASer isoacceptors, but also the selenocysteine-incorporating tRNASec
Significance in milk stimulate mTOR signalling pathway in presence of essential amino acids (EAA); enhancs EAA-stimulated cell proliferation and contribute to increased β-casein production in bovine mammary epithelial cells
