Argininosuccinic Acid. N-(4-Amino-4-carboxybutyl)amidino-L-aspartic Acid . Acid, Argininosuccinic . This amino acid is formed during the urea cycle from citrulline, aspartate and ATP. This reaction is catalyzed by argininosuccinic acid synthetase. . 0.40
Urease. Phytourease . Urea Amidohydrolase . Amidohydrolase, Urea . An enzyme that catalyzes the conversion of urea and water to carbon dioxide and ammonia. EC 3.5.1.5. . 0.37
Urea Cycle Disorders, Inborn. Disorder, Urea Cycle . Disorders, Urea Cycle . Urea Cycle Disorder . Inborn Urea Cycle Disorder . Urea Cycle Disorders . Rare congenital metabolism disorders of the urea cycle. The disorders are due to mutations that result in complete (neonatal onset) or partial (childhood or adult onset) inactivity of an enzyme, involved in the urea cycle. Neonatal onset results in clinical features that include irritability, vomiting, lethargy, seizures, NEONATAL HYPOTONIA; RESPIRATORY ALKALOSIS; HYPERAMMONEMIA; coma, and death. Survivors of the neonatal onset and childhood/adult onset disorders share common risks for ENCEPHALOPATHIES, METABOLIC, INBORN; and RESPIRATORY ALKALOSIS due to HYPERAMMONEMIA. . 0.37
Argininosuccinate Synthase. Argininosuccinate Synthetase . Synthase, Argininosuccinate . Synthetase, Argininosuccinate . An enzyme of the urea cycle that catalyzes the formation of argininosuccinic acid from citrulline and aspartic acid in the presence of ATP. Absence or deficiency of this enzyme causes the metabolic disease CITRULLINEMIA in humans. EC 6.3.4.5. . 0.35
Ureteral Neoplasms. Cancer of the Ureter . Neoplasms of Ureter . Neoplasms, Ureteral . Ureter Cancer . Ureter Neoplasms . Ureter, Cancer Of . Cancer, Ureteral . Cancers, Ureteral . Neoplasm, Ureteral . Ureter Cancers . Ureter Neoplasm . Ureteral Cancers . Ureteral Neoplasm . Cancer of Ureter . Ureteral Cancer . Cancer or tumors of the URETER which may cause obstruction leading to hydroureter, HYDRONEPHROSIS, and PYELONEPHRITIS. HEMATURIA is a common symptom. . 0.35
