An overview of the biophysics activity at Department Physics and Chemistry Emilio Segrè University Palermo is given. For forty years, focus research has been on protein structure–dynamics–function paradigm, with aim understanding molecular basis relevant mechanisms key role solvent. At least three lines are identified; main results obtained in collaboration other groups Italy abroad presented. ...

established that Ca acts as a messenger in mediating Ca, an important intracellular messenger in plants, the action of a number of hormonal and environmental is implicated in controlling diverse cellular functions signals (3–6). Cytosolic levels of Ca increase in reby regulating the activity of several enzymes. Here we sponse to gravity, light, cold temperature, salt stress, report the presence...

Recent advances in nanotechnology allow scientists to follow a biological process on a single molecule basis. These advances also raise many challenging stochastic modeling and statistical inference problems. First, by zooming in on single molecules, recent nanoscale experiments reveal that some classical stochastic models derived from oversimplified assumptions are no longer valid. Second, the...

The kinetics of reduction and intracomplex electron transfer in electrostatically stabilized and covalently crosslinked complexes between ferredoxin-NADP+ reductase (FNR) and flavodoxin (Fld) from the cyanobacterium Anabuena PCC 7119 were compared using laser flash photolysis. The second-order rate constant for reduction by 5-deazariboflavin semiquinone (dRfII) of FNR within the electrostatical...

active HNLs lacking FAD are found in some cyanogenic a-Hydroxynitrile lyase (HNL, acetone-cyanohydrin plants, e.g., flax, sorghum, rubber tree, and cassava. lyase, EC 4.1.2.37) was purified to homogeneity from Both types of HNLs show substrate specificity for eipetioles of cassava (Manihot esculenta Crantz). The puther aromatic or aliphatic cyanohydrins. rified HNL is a homotetramer with a subu...
