EC Number: 188.8.131.52
Note that this reaction equation differs from the official Enzyme Commission reaction equation for this EC number, which can be found here .
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.
Direct generic reaction:
an aliphatic α,ω-diamine + acetyl-CoA = an aliphatic N-acetyl-diamine + coenzyme A + H+ (184.108.40.206)
