Abstract: | Neurospora crassa Em 5297a can utilize sodium Β-glycerophosphate as a sole phosphorous source (in the place of KH2PO4). Under these conditions a repressible alkaline phosphatase is elaborated which has different pH optimum towards Β-glycerophosphate (10.2) and pyrophosphate (9.0) as substrates. This enzyme does not require any metal ion for its activity and could be assayed in the presence of EDTA. However, under conditions of cobalt toxicity, the activity of this enzyme is high and is decreased in copper and nickel toxicities. |
