Kinetics of L-lactate dehydrogenase from S. pyogenes, E. faecalis and L. plantarum
Actions 
Order Assays
The Lactate dehydrogenases (LDH) are key metabolic enzymes in lactic acid bacteria (LAB). The LDH ( E.C. 1.1.1.27) catalyzes the reaction of pyruvate and NADH into lactate and NAD+.We have carried out an experimental and computational study of the effects of fructose-1,6-bisphosphate (FBP), phosphate (Pi) and ionic strength (NaCl concentration) on 3 LDHs from 3 LABs studied at pH 6 and pH 7.

SysMO is a European transnational funding and research initiative on "Systems Biology of Microorganisms".
The goal pursued by SysMO was to record and describe the dynamic molecular processes going on in unicellular microorganisms in a comprehensive way and to present these processes in the form of computerized mathematical models.
Systems biology will raise biomedical and biotechnological research to a new quality level and contribute markedly to progress in understanding. Pooling European research ...

Challenge: Comparative analyses, as demonstrated by comparative genomics and bioinformatics, are extremely powerful for (i) transfer of information from (experimentally) well-studied organisms to the other organisms, and (ii) when coupled to functional and phenotypic information, insight in the relative importance of components to the observed differences and simalities. The central principle of this proposal is that important aspects of the functional differences between organisms derive not ...
