1. Ureases display biological effects independent of enzymatic activity. Is there a connection to diseases caused by urease-producing bacteria?
Ureases are enzymes from plants, fungi and bacteria that catalyze the hydrolysis of urea to form ammonia and carbon dioxide. While fungal and plant ureases are homo-oligomers of 90-kDa subunits, bacterial ureases are multimers of two or three subunit complexes. We showed that some isoforms of jack bean urease, canatoxin and the classical urease, bind to glyc

3. A canatoxina induz secreção de histamina de mastocitos peritoneais de ratos
Canatoxin (CNTX), a toxic protein extracted from the mature seeds of Canavalia ensiformis, induces secretion in several cells systems. Concanavalin A (Con A), the lectin that is also present in Canavalia ensiformis seeds, induces histamine secretion from rats mast cells. AIthough being two completely distinct principIes, CNTX and Con A share some pharmacolog

4. Investigações preliminares sobre as alterações sexo-dependentes da glicemia produzidas por canatoxina em ratos
1. The chronical administration of canatoxin (0.1mg/kg of ac:tive protein) to intac:t maIe and femaIe rats induced a pronounced sex-reIated dependent aIteration upon the bIood glucose Ievels of the animaIs. Thus, whiIe the males exhibited hypergIycemia the femaIes showed hypoglycemia. 2. A rise in the circuIating glucose IeveIs comparable to that seen in maI
