The systematic name of this enzyme class is L-arginine iminohydrolase.
Other names in common use include arginine dihydrolase, citrulline iminase, and L-arginine deiminase.
This enzyme is widely expressed in bacteria, including streptococcus and actinomyces.
The bacterial arginine deiminase expression could be regulated by various environmental factors.
Recently, a new enzyme that catalyzes the chemical reaction As of late 2007, 7 structures have been solved for this class of enzymes, with PDB accession codes 1LXY, 1RXX, 1S9R, 2A9G, 2AAF, 2ABR, and 2ACI.
