The intrinsic or natural fluorescence of proteins is perhaps the most complex area of biochemical fluorescence. Fortunately the fluorescent amino acids, phenylalanine, tyrosine and tryptophan are relatively rare in proteins. Tr- tophan is the dominant intrinsic fluorophore and is present at about one mole % in protein. As a result most proteins contain several tryptophan residues and even more tyrosine residues. The emission of each residue is affected by several excited state processes including spectral relaxation, proton loss for tyrosine, rotational motions and the presence of nearby quenching groups on the protein. Additionally, the tyrosine and tryptophan residues can interact with eac...

Leading scientists argue for a new paradigm for cancer research, proposing a complex systems view of cancer supported by empirical evidence. Current consensus in cancer research explains cancer as a disease caused by specific mutations in certain genes. After dramatic advances in genome sequencing, never before have we known so much about the individual cancer cell--and yet never before has it been so unclear what to do with this knowledge. In this volume, leading researchers argue for a new theory framework for understanding and treating cancer. The contributors propose a complex systems view of cancer, presenting conceptual building blocks for a new research paradigm supported by empirical...
Ca2+ signaling in neurons is characterized by highly restricted and dynamic gradients called Ca2+ waves, spikes, transients and puffs depending upon their corresponding spatial and temporal features. Based on this strict segmentation the Ca2+ ion provides a versatile basis for complex signaling in neuronal subcompartments with a spatial resolution of micro- and nanodomains. The multitude of Ca2+-regulated processes requires specialized downstream processing machinery, translating the Ca2+ signal into alterations of cellular processes. The broad range of different Ca2+-triggered phenomena in neurons, ranging from neurotransmission to gene expression, is reflected by the existence of a multitu...
Molecular and Cellular Enzymology addresses not only experienced enzymologists but also students, teachers and academic and industrial researchers who are confronted with enzymological problems during their fundamental or applied research. In this field there is an urgent need for training in order to meet the requirements of both research and industrial endeavours. This book consists of several levels. Practical aspects and elementary explanations are given for the benefit of non-specialists’ and students’ understanding. In order to facilitate the task of students, two typographies have been adopted. The main text corresponds to basic knowledge, whereas text in a smaller font provides m...
This book presents a selection of revised full papers accepted for presentation at the First International Conference on Biology, Informatics, and Mathematics, JOBIM 2000, held in Montpellier, France, in May 2000. The 13 papers included in the book were selected after two rounds of reviewing and revision from a total of 67 submissions. Among the topics addressed are algorithms, comparative genomics, evolution, phylogeny, databases, knowledge processing, genome anotation, graph theory, combinatorial mathematics, macromolecular structures, RNA and proteins, metabolic pathways and regulatory networks, and statistics and classification.
The enormous and varied role of calcium in living systems is now widely appreciated by both cell biologists and clinicians. The identification and characterisation of new calcium binding proteins and regulatory pathways is matched by the recognition of the involvement of calcium binding proteins in a growing number of disease states. This book is intended to introduce clinicians to fundamental biological research, whilst at the same time attracting researchers to the clinical world. The publication of the book coincides with the elucidation of the complete Human Genomic Sequence. As a result of this, scientists now have access to an unprecedented array of data, from which new calcium binding...
This volume summarises the lecture and poster sessions of a NATO advanced workshop held in Edinburgh, July 15th-19th, 1985. The workshop was held to bring together plant scientists of many different disciplines but who share a common interest in the regulatory role of calcium in plant development. Although this volume covers the formal proceedings, an equal length of time was devoted to discussion both in large and small groups. A little of the flavour of the directions and character of the discussions will be found in the final article by David Clarkson which was written to cover this other wise uncovered area of the workshop. The volume reflects much of the current excitement in the field of plant calcium research. Many of the participants are pioneers in their res pective areas and the extent to which the last five years has seen a drama tic unfolding, a complete inversion of the role of calcium from simple macro nutrient to major metabolic and developmental controller is recounted here. The material is new and much of it unpublished. In plant physiology, the eighties may yet be designated the decade of calcium.
