Gluconeogenic carbon metabolism

Abstract

10.1 Introduction Most filamentous fungi have a saprophytic lifestyle where growth entails the utilization of environmental compounds as nutrients. These include sources of carbon, nitrogen, phosphorus, and sulfur. Of particular relevance here is the ability of fungi to metabolize a very diverse range of carbon compounds. Where a substrate is available as the sole carbon source then all cellular components must be synthesized from this compound via appropriate metabolic pathways. This, therefore, requires the organism to have the ability to rearrange the expression of gene-encoding enzymes catalyzing the appropriate steps in the pathways according to the substrates available. Commonly there ..
