Proline–tRNA ligase

In enzymology, a proline–tRNA ligase or proline—tRNA ligase is an enzyme that catalyzes the chemical reaction
The 3 substrates of this enzyme are ATP, -proline, and tRNA, whereas its 3 products are AMP, diphosphate, and -prolyl-tRNA.
This enzyme participates in arginine and proline metabolism and aminoacyl-tRNA biosynthesis.

Nomenclature

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 -proline:tRNA ligase. Other names in common use include prolyl-tRNA synthetase, prolyl-transferRNA synthetase, prolyl-transfer ribonucleate synthetase, proline translase, prolyl-transfer ribonucleic acid synthetase, prolyl-s-RNA synthetase, and prolinyl-tRNA ligase.
