Figure 2From: Extraction of elementary rate constants from global network analysis of E. coli central metabolismAllosteric enzymes consisting of an allosteric segment (dark shaded area) and an enzymatic reaction segment. (A): Pyruvate kinase, where the number of allosteric sites and catalytic sites are 4 and 1, respectively [39]. (B): Phosphofructokinase, where the number of allosteric sites is 2 according to [39]. Non-integral reaction orders are assumed for two substrates due to fractal properties caused by enzyme conformational changes [43].Back to article page
