Catabolite repression
-
Optimal glucose metabolism is central to the growth and development of cells. In microbial eukaryotes, carbon catabolite repression (CCR) mediates the preferential utilization of glucose, primarily by repressing alternate carbon source utilization.

A thermal tolerant stereo-complex poly-lactic acid (SC-PLA) can be made by mixing Poly-D-lactic acid (PDLA) and poly-L-lactic acid (PLLA) at a defined ratio. This environmentally friendly biodegradable polymer could replace traditional recalcitrant petroleum-based plastics.

We have investigated the crr gene of Streptomyces coelicolor that encodes a homologue of enzyme IIAGlucose of Escherichia coli, which, as a component of the phosphoenolpyruvate-dependent sugar phosphotransferase system (PTS) plays a key role in carbon regulation by triggering glucose transport, carbon catabolite repression, and inducer exclusion. As in E. coli, the crr gene of S. coelicolor is genetically associated with the ptsI gene that encodes the general phosphotransferase enzyme I.

Histidine-containing protein (HPr) is a central metabolic sensor in low-GC Gram-positive bacteria and plays a dual role in sugar uptake by the phos-phoenolpyruvate–sugar phosphotransferase system and in transcriptional control during carbon catabolite repression. The latter process is mediated by interaction between HPr and the carbon catabolite repression master transcription regulator, carbon catabolite protein A (CcpA), a member of the LacI-GalR family of DNA-binding proteins.

The phosphotransferase system inEscherichia coliis a transport and sen-sory system and, in this function, is one of the key players of catabolite repression. Mathematical modelling of signal transduction and gene expres-sion of the enzymes involved in the transport of carbohydrates is a promis-ing approach in biotechnology, as it offers the possibility to achieve higher production rates of desired components.
