L-arginine-O-ethyl ester and L-homo-arginine are extremely poor substrates for isoform AK1 with only 3.5% and 2% of the L-arginine reaction rate. L-Nalpha-acetyl-arginine, agmatine, creatine, 4-guanidino butyric acid, N7-methyl-arginine and N7-nitro-arginine are no substrates for isoform AK1. Minor substrates for isoform AK2 are L-Nalpha-acetyl-arginine and 4-guanidino butyric acid with 1.5% and 1.9% of the L-arginine reaction rate, respectively. Agmatine, creatine, L-N7-methyl-arginine and L-N7-nitro-arginine are no substrates for isoform AK2 |
