Escherichia coli K-12 substr. MG1655 : alanyl-tRNA synthetase and DNA-binding transcriptional repressor Inferred from experiment : alaS

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.
