Are the trapping dynamics in Photosystem II sensitive to QA redox potential?
(2001)Removal of the manganese complex from photosystem II (PSII) causes a 145 meV shift in the redox potential of the plastoquinone QA [Biochim. Biophys. Acta 1229 (1995) 193; Photosynthetica 27 (1–2) (1992) 89; Biochim. Biophys. ... -
Effect of Nonionic Detergents on Lipoxygenase Catalysis
(1994)In many studies on lipoxygenase catalysis, nonionic detergents are used to obtain an optically transparent solution of the fatty acid substrate. In order to resolve some controversies that exist with regard to the ... -
Dynamic instability of microtubules: Monte Carlo simulation and application to different types of microtubule lattice
(1993)Dynamic instability is the term used to describe the transition of an individual microtubule, apparently at random, between extended periods of slow growth and brief periods of rapid shortening. The typical sawtooth growth ... -
Opposite-end behaviour of dynamic microtubules
(1991)Microtubules are dynamic polar structures with different kinetic properties at the two ends. The inherent asymmetry of the microtubule lattice determines that the relationship between the addition reaction of tubulin-GTP ... -
Microtubule dynamic instability: numerical simulation of microtubule transition properties using a Lateral Cap model
(1990)We present a numerical formulation for the dynamic instability of microtubules involving the stabilisation of growing microtubules by a single layer of tubulin-GTP, with GTP hydrolysis effectively coupled to tubulin-GTP ... -
A simple formulation of microtubule dynamics: quantitative implications of the dynamic instability of microtubule
(1989)A simple formulation of microtubule dynamic instability is presented, which is based on the experimental observations by T. Horio and H. Hotani of coexisting, interconverting growing and shrinking microtubules. Employing ... -
A Lateral Cap model of microtubule dynamic instability
(1989)The co-existence and interconversion of growing and shrinking microtubules have been termed ‘dynamic instability’, and have been directly observed to occur under a variety of conditions in vitro and in vivo. Previous ... -
The effect of podophyllotoxin on microtubule dynamics
(1989)We have investigated the effects of podophyllotoxin on the dynamic properties of microtubules assembled from pure tubulin dimer. Excess podophyllotoxin causes the complete disassembly of microtubules, through formation of ... -
Dynamic properties of microtubules at steady state of polymerisation
(1987)Microtubules of tubulin dimer, polymerised in vitro to steady-state are shown to incorporate tubulin rapidly and extensively. The method involves adding [3H]-GTP to microtubules at steady state, and analysing for ... -
On the relationship between nucleotide hydrolysis and microtubule assembly : Studies with a GTP-regenerating system
(1987)The assembly of pure tubulin dimer has been studied in two buffer systems (containing low and high glycerol/Mg), using a regeneration system protocol to assess the amount of GDP-tubulin in the assembling polymer. For both ... -
Three-dimensional image reconstruction of helical aggregates of trypsin modified elongation factor EF-Tu from Escherichia coli
(1986)The three-dimensional structure of trypsin-modified EF-Tu polymers was analyzed to a resolution of 30 Å with electron image reconstruction techniques after negative staining. In a 70% saturated ammonium sulfate solution ... -
Immunocytochemical localization of the elongation factor Tu in E. coli cells
(1984)The localization of the elongation factor Tu (EF-Tu) in ultrathin cryosections of E. coli cells was determined with the electron microscope using a highly specific immunological labellin technique. EF-Tu is distributed ... -
An electron microscopic investigation of the structure of Alfalfa mosaic virus
(1980)Minimum beam electron microscopy and the three-dimensional reconstruction technique were used to analyse negatively stained Alfalfa mosaic virus particles and polymers of reassembled coat protein. Three strains of the virus ... -
Low-dose electron image reconstruction of negatively stained contractile phage sheath from Bacillus subtilis (PBS-Z)
(1979)The structure of the contractile sheath of the defective phage from B. subtilis (PBS-Z) has been investigated by low-dose electron microscopy and image reconstruction. The extended and contracted sheath particles were ... -
Missing Men in Education
(Trentham Books, 2006)This book reports on the ten years' research by the authors into men in teaching. There is much concern about boys' underachievement in schools compared to girls. But attributing this to the dearth of men in teaching is ... -
Wide optical lenses for atomic beams.
(IEEE, 2009)The field of atom-optics offers considerable potential in fundamental and applied physics, both for imaging atoms and their deposition (to create nano-structures). Here we work in the paraxial approximation throughout and ... -
The role of parenting classes for young fathers in prison : a case study
(2004)This article considers the role of parenting classes for young men in prison. Using a case study of one course delivered at a young offender institution, significant aspects of the content and delivery are identified. The ... -
