    Description: The active portion of the alpha subunit of pyruvate dehydrogenase in rat frontal cortex was elevated after a training experience. No change in total pyruvate dehydrogenase activity was observed. The phosphorylation in vitro of pyruvate dehydrogenase (band F-2) was also elevated after training. Since activation of pyruvate dehydrogenase requires its dephosphorylation, the following sequence is proposed. Training alters frontal cortex and reduces the phosphate content of pyruvate dehydrogenase in vivo; this leads to enzyme activation; and an increase in back-titration of sites available for phosphorylation in vitro.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Morgan, D G -- Routtenberg, A -- MH25281/MH/NIMH NIH HHS/ -- New York, N.Y. -- Science. 1981 Oct 23;214(4519):470-1.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7291989" target="_blank"〉PubMed〈/a〉

    Description: The relationship between the actin-activated adenosinetriphosphatase activity of smooth muscle myosin and the extent of myosin light chain phosphorylation is nonlinear. It is suggested that the phosphorylation of the two heads of smooth muscle myosin is an ordered process and that the two heads are influenced by cooperative interactions.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Persechini, A -- Hartshorne, D J -- HL 23615/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 1981 Sep 18;213(4514):1383-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6455737" target="_blank"〉PubMed〈/a〉
