Abstract
In biotechnologically important fungus Aspergillus niger, plasma membrane H+-ATPase plays a significant role in controlling intracellular pH and global regulation of metabolism. The activity of H+-ATPase is regulated by calcium/calmodulin-dependent protein kinase phosphorylation. After cloning and characterisation of calcium/calmodulin-dependent protein kinase, its involvement in signal transduction will be determined. Cyclic-AMP and phospholipid signal transduction cross talk will be determined using a novel recombinant system for detection of cytosolic free calcium ions and cAMP "in vivo" in A. niger.
