EC Number: 188.8.131.521
Enzymes and Genes:
(NAD(P)-dependent glycerol-1-phosphate dehydrogenase : egsA ( Methanothermobacter thermautotrophicus Delta H )
In Pathway: CDP-archaeol biosynthesis
The reaction direction shown, that is, A + B ↔ C + D versus C + D ↔ A + B, is in accordance with the Enzyme Commission system.
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.
