Adenylate cyclase from Brevibacterium liquefaciens. III. In situ regulation of adenylate cyclase by pyruvate.
In the presence of DL-alanine intracellular cyclic AMP in nonproliferating cells of Brevibacterium liquefaciens increased rapidly to the maximum level of approximately 180 muM, and extracellular cyclic AMP increased to 100 muM within 4 hr at 25 degrees . Adenylate cyclase (EC 4.6.1.1) induction was not observed during this incubation. The concentration of pyruvate in the total culture increased...
متن کاملBrevibacterium liquefaciens adenylate cyclase and its in vivo stimulation by pyruvate.
Adenylate cyclase of Brevibacterium liquefaciens depends on pyruvate for activity. Growing in a simple medium containing glucose and DL-alanine, the microorganism excreted pyruvate, which reached 20 mM in the medium at stationary phase. Using [3H]adenosine to label the adenosine 5'-triphosphate pool, we showed that pyruvate in the medium stimulated adenylate cyclase of B. liquefaciens in vivo, ...
متن کاملE 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 کاملDetergent-dispersed Adenylate Cyclase from Rat Brain
Some properties of particulate and detergent-dispersed preparations of adenylate cyclase from rat brain have been studied. The activity of the particulate enzyme was greater with Mn2f than with Mg2+ and the activity in the presence of either cation was enhanced by For nonionic detergents. In the presence of the non-ionic detergent Lubrol-PX, enzyme activity was further enhanced by dithiothreito...
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...
