Subsystem: Arginine and Ornithine Degradation
This subsystem's description is:
There are various routes employed by bacteria to utilize arginine. While the first arginine catabolic operon was reported in 1990 on the arginine deiminase (ADI) pathway, the past decade has proven to be enormously productive regarding molecular characterization of various arginine catabolic operons and regulation in bacteria.
In this Subsystem we summarize four major arginine catabolic pathways:
1) arginase pathway,
2) arginine succinyltransferase (AST) pathway (the major route of arginine utilization as the carbon and nitrogen source under aerobic conditions),
3) arginine decarboxylase/agmatinase/agmatine deiminase pathway (serves to supply putrescine when arginine is abundant),
4) arginine deiminase (ADI) pathway ( there is separate Subsystem in the SEED for ADI: Arginine Deiminase Pathway, Author: master:OlgaZ) (provides ATP to support slow growth under anaerobic conditions).
=======Variant codes: ===============
1.1 - Arginine succinyltransferase (AST) pathway (astCADBE operon);
1.2 – Arginase pathway (rocRDEF or rocRDGA operons)
1.3 – Arginine decarboxylase/agmatinase/agmatine deiminase pathway (SpeA or AdiA +SpeB or AguAB);
1.4 - Arginine deiminase (ADI) pathway;
1.1234 - All routes above are present and complete;
1.12x34 - All routes above are present and complete except arginase pathway (code1.2), where some genes are missing.
“x” after the number stands for incomplete pathway
