Table 10 Biochemical properties of selected L-arginine decarboxylases of freshwater and marine cyanobacteria, and their similarity to L-arginine decarboxylases from E. coli.

From: Bioinformatic evaluation of L-arginine catabolic pathways in 24 cyanobacteria and transcriptional analysis of genes encoding enzymes of L-arginine catabolism in the cyanobacterium Synechocystis sp. PCC 6803

Strain Database entry AA MM (kDa) pI Group III decarboxylase: E. coli P28629 (biodegradable type) 755 aa; 84.4 kDa; pI 5.12 Group IV decarboxylase: E. coli P21170 (biosynthetic type) 658 aa; 73.9 kDa; pI 4.83

  1. P28629 represents a biodegradable and inducible L-arginine decarboxylase (group III); P21270 represents a biosynthetic and constitutively expressed L-arginine decarboxylase (group IV) in E. coli [26]. Score values were calculated with the ClustalW software [62]. The L-arginine decarboxylases in the yellow, blue, green, and red cluster are identical to those L-arginine decarboxylases given in Fig. 3.
