MetaCyc Reaction: 6.1.1.21

Superclasses: Reactions Classified By Conversion Type Simple Reactions Chemical Reactions
Reactions Classified By Substrate Macromolecule Reactions Polynucleotide-Reactions RNA-Reactions tRNA-Reactions tRNA-Charging-Reactions

EC Number: 6.1.1.21

Enzymes and Genes:

Escherichia coli K-12 substr. MG1655 : histidyl-tRNA synthetase Inferred from experiment : hisS

In Pathway: tRNA charging

The reaction direction shown, that is, A + B ↔ C + D versus C + D ↔ A + B, is in accordance with the direction in which it was curated.

Most BioCyc compounds have been protonated to a reference pH value of 7.3, and some reactions have been computationally balanced for hydrogen by adding free protons. Please see the PGDB Concepts Guide for more information.

Mass balance status: Balanced.

Enzyme Commission Primary Name: histidine—tRNA ligase

Enzyme Commission Synonyms: histidyl-tRNA synthetase, histidyl-transfer ribonucleate synthetase, histidine translase

Standard Gibbs Free Energy (ΔrG in kcal/mol): -92.58356 Inferred by computational analysis [Latendresse13]
