Membrane traffic: Cycling lipids
One of the more fascinating problems in biology is to understand the nerve signalling that enables us to think and feel. The transmission of nerve impulses across synapses is accomplished by the release of signalling molecules, known as neurotransmitters, at nerve terminals. Neurotransmitters are stored in synaptic vesicles and, after the nerve has received the appropriate stimulus, they are re...
متن کاملAdventures with membrane lipids.
It is a very great honour to have been awarded the Biochemical Society’s Morton Lectureship for 1994. T o be chosen by one’s peers for an award of this stature is indeed the ultimate reward for one’s life’s work, even more so when one considers the high level of achievement reached by Professor R.A. Morton himself and by the previous awardees. This award is particularly gratifying to me in reca...
متن کاملEnzyme function and membrane lipids.
Biomembranes are built upon a lipid bimolecular ' matrix and intrinsic membrane enzymes can penetrate partially or totally span this bilayer, e.g. the cytochrome oxidase (Frey et al., 1978). Protein-lipid interactions are therefore important for such enzymes, determining their organization and their function (Gennis & Jonas, 1977; Sandermann, 1978; Chapman et al., 1979). In recent years an incr...
متن کاملLipids and Membrane Lateral Organization
Shortly after the elucidation of the very basic structure and properties of cellular membranes, it became evident that cellular membranes are highly organized structures with multiple and multi-dimensional levels of order. Very early observations suggested that the lipid components of biological membranes might be active players in the creation of these levels of order. In the late 1980s, sever...
متن کاملRhizosphere bacterial carbon turnover is higher in nucleic acids than membrane lipids: implications for understanding soil carbon cycling
Using a pulse chase (13)CO2 plant labeling experiment we compared the flow of plant carbon into macromolecular fractions of rhizosphere soil microorganisms. Time dependent (13)C dilution patterns in microbial cellular fractions were used to calculate their turnover time. The turnover times of microbial biomolecules were found to vary: microbial RNA (19 h) and DNA (30 h) turned over fastest foll...
