L-arginine deiminases and L-arginine amidinotransferases belong to a superfamily of enzymes that catalyze the modification of guanidino groups. The number of amino acid residues, the molecular mass, and the calculated isoelectric point is given. Moreover, the similarity of the selected reference enzymes to Sll1336 from Synechocystis sp. PCC 6803 is given. Values for % identity and similarity to Sll1336 were determined with the EMBOSS Pairwise alignment algorithm [65]. The percentage identity and similarity does not include weakly similar amino acid residues.
