Abstract:
In crude conidia extracts of Aspergillus niger, 650 pmol AMP/mg protein was found but no ADP or ATP could be detected. Cell‐free extracts from the conidia produce ATP in the presence of AMP and phosphoenolpyruvate. The system is Mg2+ ‐dependent and highly stimulated by increases in the viscosity of the incubation media. The examination of enzymes involved in the ATP synthesis, revealed the presence of adenylate kinase (EC 2.7.4.3) and pyruvate kinase (EC 2.7.1.40) activity. The pyruvate kinase is stimulated in viscous incubation media. A 30% polyethyleneglycol concentration was found to be an optimal viscous medium. Adenylate kinase was unaffected by viscosity changes.
