text: However, since L-arginine amidinotransferases have so far only been shown to function in antibiotic or toxin biosynthesis in prokaryotes and since an L-arginine deiminase activity has been detected in several fresh water cyanobacteria [17–20], we think that it is more likely that the corresponding gene in the nine cyanobacteria (Tables 4, 7, and 8) encodes an L-arginine deiminase and not an L-arginine amidinotransferase.
