概要

• 論文の詳細を見る

• Guanidinobutyrase (EC 3.5.3.7) involved in the arginine oxygenase pathway of Brevibacterium helvolum IFO 12073 was found to catalyze also the hydrolysis of 2-ketoarginine (2-keto-5-guanidinovalerate) to 2-ketoornithine (2-keto-5-aminovalerate) and urea, the second step of the arginine aminotransferase pathway. No other enzyme that degraded 2-ketoarginine was found in cells grown on L-arginine. The enzyme hydrolyzed 2-ketoarginine with a relative rate of about 0.7% of that toward 4-guanidinobutyrate. The K_m for 2-ketoarginine was 33mM.
