Reaction: L-arginine + 1-amino-1-deoxy-scyllo-inositol 4-phosphate = L-ornithine + 1-guanidino-1-deoxy-scyllo-inositol 4-phosphate
Other name(s): L-arginine:inosamine-P-amidinotransferase; inosamine-P amidinotransferase; L-arginine:inosamine phosphate amidinotransferase; inosamine-phosphate amidinotransferase
Systematic name: L-arginine:1-amino-1-deoxy-scyllo-inositol-4-phosphate amidinotransferase
Comments: 1D-1-Guanidino-3-amino-1,3-dideoxy-scyllo-inositol 6-phosphate, streptamine phosphate and 2-deoxystreptamine phosphate can also act as acceptors; canavanine can act as donor.
