EC Number:

Enzymes and Genes:
arginine decarboxylase, degradative Inferred from experiment : adiA
arginine decarboxylase, biosynthetic Inferred from experiment : speA

In Pathway: L-arginine degradation III (arginine decarboxylase/agmatinase pathway) , putrescine biosynthesis I , arginine dependent acid resistance

Reaction Locations: periplasmic space (sensu Gram-negative Bacteria), cytosol

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.

Enzyme Commission Primary Name: arginine decarboxylase

Enzyme Commission Synonyms: SpeA, L-arginine carboxy-lyase

This is the first step in the biosynthesis of spermidine from arginine.

Enzyme Commission Summary:
A pyridoxal-phosphate protein.
