Modification of Escherichia coli phosphofructokinase-2 (Pfk-2) with N-(1-pyrenil)maleimide results in an enzyme form that is inactive. However, the rate of modification is drastically reduced in the presence of the allosteric effector MgATP. The stoichiometry of the label incorporation was found

Modification of Escherichia coli phosphofructokinase-2 (Pfk-2) with pyrene maleimide (PM) results in a rapid inactivation of the enzyme. The loss of enzyme activity correlates with the incorporation of 2 mol of PM/mol of subunit and the concomitant dissociation of the

Telomerase activity is repressed in normal human somatic cells, but is activated in most cancers, suggesting that telomerase may be an important target for cancer therapy. Agents that interact selectively with telomerase are anticipated to exert specific action on cancer

Human deoxycytidine kinase (dCK) phosphorylates both pyrimidine and purine deoxynucleosides, including numerous nucleoside analogue prodrugs. Energy transfer studies of transfer between Trp residues of dCK and the fluorescent probe N-(1-pyrene)maleimide (PM), which specifically labels Cys residues in proteins, were performed.
