The transient and steady-state behavior of a reversible covalent modification system is examined, finding that amplification of the response to a stimulus can provide additional sensitivity in biological control, equivalent to that of allosteric proteins with high Hill coefficients.

This dissertation aims to provide a history of web exceptionalism from 1989 to 2002, a period chosen in order to explore its roots as well as specific cases up to and including the year in which descriptions of “Web 2.0” began to circulate.

The suggestion of Lipmann' that the energy required to drive this reaction to the right came from adenosine triphosphate has been supported by the extensive work and an analysis of why this linking of amino acids presents such formidable difficulties is revealing.

It was found, however, that a sudden increase also elicits a response, namely supercoordinated swimming, which demonstrates that chemotaxis is achieved by modulation of the incidence of tumbling both above and below its steady-state value.

The conservation of the small angular change in vitro suggests that the inter-subunit rotation may have relevance to the understanding of the mechanism of transmembrane signal transduction in vivo.
Catalytic mechanism of NADP(+)-dependent isocitrate dehydrogenase: implications from the structures of magnesium-isocitrate and NADP+ complexes.

The coenzyme-binding site confirms the fundamentally different evolution of the isocitrate dehydrogenase-like and the lactate dehydrogenases-like classes of nucleotide-binding proteins.
