E VALUATION OF ADENYLATE CYCLASE ACTIVITY IN MITRAL VALVE PROLAPSE
The term mitral valve prolapse (MVP) is used for a particular subset of patients with hyperadrenergic dysautonomia. It occurs when part of a leaflet or both leaflets of the mitral valve extend above the plane of the atrioventricular junction during ventricular systole. The adenylate cyclase activity in MVP dys-autonomia was studied by extraction of enzyme from the erythrocytes from 62 norma...
متن کاملadenylate cyclase activity
Adipocyte membranes from control rats exhibited a functional Gi (inhibitory guanine-nucleotide-binding protein) activity which could be assessed either by the inhibitory action of low concentrations of guanosine 5-[/Jy-imido]triphosphate (p[NH]ppG) upon forskolin-stimulated adenylate cyclase activity or by the inhibitory action of high concentrations of GTP upon isoprenaline-stimulated adenylat...

متن کاملAdenylate cyclase activity in Neurospora crassa.
Adenylate cyclase, the enzyme responsible for cyclic adenylate synthesis has been found in membrane fractions of animal cells (l-4). This enzyme system is stimulated by several hormones, showing a wide range of specificity. The occurrence of a similar enzyme activity has been also demonstrated in Escherichia coli and Bacillus liquejaciens (5-7)) but in these organisms the mechanism that regulat...
متن کاملPhospholipase A activity of adenylate cyclase toxin mediates translocation of its adenylate cyclase domain.
Adenylate cyclase toxin (ACT or CyaA) plays a crucial role in respiratory tract colonization and virulence of the whooping cough causative bacterium Bordetella pertussis Secreted as soluble protein, it targets myeloid cells expressing the CD11b/CD18 integrin and on delivery of its N-terminal adenylate cyclase catalytic domain (AC domain) into the cytosol, generates uncontrolled toxic levels of ...
