Regulation of pyruvate kinase • If glycolysis gets past the phosphofructokinase step, then regulation is at the pyruvate kinase step. • Pyruvate kinase activity is inhibited under low glucose conditions by covalent phosphorylation • If fructose 1,6 bisphosphate is formed, it acts a allosteric feed-

cyclic-AMP (cAMP) cascade protein kinase A (PKA). PKA
mcb.berkeley.eduThis regulatory enzyme contains two distinct enzyme activities in two active sites on one single polypeptide chain. FPK-2 gets phosphorylated in the cAMP cascade in the liver. The effect of phosphorylation generally depends on the enzyme, but usually activity either goes up or down. When this giant

mcb.berkeley.edu• The enzyme phosphorylase catalyzes glycogen breakdown, while glycogen synthase catalyzes polymerization. • Regulation is achieved by several hormones, such as glucagon (from the pancreas) and epinephrine (from the adrenal medulla). Binding of epinephrine or glucagon to their receptors activates adenyl cyclase. cAMP binds to the regulatory ...
Mathematical Modelling in Systems Biology: An Introduction
www.math.uwaterloo.cachemical kinetics, providing rate laws for biochemical processes (i.e. enzyme-catalysed reactions and cooperative binding). An optional section treats common approximation methods. Chapter 4 introduces techniques for analysis of differential equation models, including phase plane analysis, stability, bifurcations, and sensitivity analysis.
