This view shows enzymes only for those organisms listed below, in the list of taxa known to possess the pathway. If an enzyme name is shown in bold, there is experimental evidence for this enzymatic activity.
|Superclasses:||Degradation/Utilization/Assimilation → Amino Acids Degradation → Proteinogenic Amino Acids Degradation → L-arginine Degradation|
Some taxa known to possess this pathway include : Arthrobacter globiformis , Arthrobacter sp. KUJ8602 , Brevibacterium helvolum , Leishmania donovani , Pimelobacter simplex , Streptomyces griseus , Streptomyces violaceochromogenes
Several Actinobacteria, including Streptomyces griseus, Streptomyces violaceochromogenes, Brevibacterium helvolum and Arthrobacter globiformis can utilize L-arginine as the sole source for carbon and nitrogen utilizing a pathway that involves the intermediate 4-guanidinobutyramide [Van62, Van62a, Yorifuji89, Yorifuji95]. The same pathway was also observed in the eukaryotic parasite Leishmania donovani [Bera87].
In this pathway L-arginine is degraded via 4-guanidinobutyramide, 4-guanidinobutyrate, and 4-aminobutanoate, which is eventually degraded via succinate semialdehyde into succinate, and fed into the TCA cycle I (prokaryotic) (see the pathway superpathway of 4-aminobutyrate degradation) [Hatt56, Nguyen66]. ammonia and urea are produced during this process, providing the direct nitrogen source for the organism (urea can be used after it is split by the enzyme urease into ammonia and CO2).
Variants: L-arginine degradation I (arginase pathway) , L-arginine degradation II (AST pathway) , L-arginine degradation III (arginine decarboxylase/agmatinase pathway) , L-arginine degradation IV (arginine decarboxylase/agmatine deiminase pathway) , L-arginine degradation V (arginine deiminase pathway) , L-arginine degradation VI (arginase 2 pathway) , L-arginine degradation VII (arginase 3 pathway) , L-arginine degradation VIII (arginine oxidase pathway) , L-arginine degradation IX (arginine:pyruvate transaminase pathway) , L-arginine degradation XI , L-arginine degradation XII , L-citrulline-nitric oxide cycle , superpathway of L-arginine and L-ornithine degradation , superpathway of L-arginine, putrescine, and 4-aminobutyrate degradation
