Calcium activates an electrogenic proton pump in neurospora plasma membrane.
نویسنده
چکیده
Calcium ionophoresis into coenocytic cells of Neurospora crassa activates the plasma membrane proton pump as measured by current-voltage analysis. This is direct evidence that intracellular calcium regulates the activity of a key transport enzyme found in higher plants and fungi.

The neurospora plasma membrane ATPase is an electrogenic pump.
Biochemicalical evidence is presented which demonstrates that the Neurospora crassa plasma membrane ATPase (ATP phosphohydrolase, EC 3.6.1.3) is an electrogenic pump. The electrical potential across the Neurospora plasma membrane, as monitored by [14C]SCN- uptake by isolated Neurospora plasma membrane vesicles, is markedly increased interior positive under conditions of ATP hydrolysis catalyzed...
متن کاملA potassium-proton symport in Neurospora crassa
Combined ion flux and electrophysiological measurements have been used to characterized active transport of potassium by cells of Neurospora crassa that have been moderately starved of K+ and then maintained in the presence of millimolar free calcium ions. These conditions elicit a high-affinity (K1/2 = 1-10 microM) potassium uptake system that is strongly depolarizing. Current-voltage measurem...
متن کاملActive transport of calcium in Neurospora plasma membrane vesicles.
Functionally inverted plasma membrane vesicles isolated from the eukaryotic microorganism Neurospora crassa catalyze Mg2+/ATP-dependent Ca2+ uptake. Inhibitors induced efflux studies and isotope-exchange experiments indicate that the Ca2+ is accumulated inside the vesicles against a concentration gradient of about 40-fold, and that the majority of the transported Ca2+ is present essentially in ...
متن کاملThe insect V-ATPase, a plasma membrane proton pump energizing secondary active transport: molecular analysis of electrogenic potassium transport in the tobacco hornworm midgut.
Goblet cell apical membranes in the larval midgut of Manduca sexta are the site of active and electrogenic K+ secretion. They possess a vacuolar-type ATPase which, in its immunopurified form, consists of at least nine polypeptides. cDNAs for the A and B subunits screened by monoclonal antibodies to the A subunit of the Manduca V-ATPase or by hybridisation with a cDNA probe for a plant V-ATPase ...
متن کاملElectrogenic proton pump in Nitella and the effect of calcium.
The hyperpolarisation of the membrane potential in Characeae above that of the diffusion potential is explained by the operation of the electrogenic proton pump. We studied the interaction of calcium with the functioning of the pump. The membrane potential was measured using the standard microelectrode technique. An increase in the calcium concentration resulted in depolarisation, its magnitude...
