MetaCyc Reaction: 1.5.1.9

Superclasses: Reactions Classified By Conversion Type Simple Reactions Chemical Reactions
Reactions Classified By Substrate Small-Molecule Reactions

EC Number: 1.5.1.9

Enzymes and Genes:
saccharopine dehydrogenase Inferred from experiment ( Bos taurus )
α-aminoadipic semialdehyde synthase, mitochondrial Inferred from experiment : AASS ( Homo sapiens )

In Pathway: lysine degradation II (mammalian)

Reaction Locations: NIL

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.
