The processes of activation and deactivation of ribulose-1,5-bisphosphate carboxylase purified from wheat have been investigated. Two forms of the enzyme are indistinguishable in terms of ribulose-1,5-bisphosphate carboxylation and oxidation but exhibit different rates of activation. One form is slowly activated in saturating CO2 and Mg2+ at moderate(More)
Wheat ribulose bisphosphate carboxylase can be converted from the slowly activating into the rapidly activating form by heat or effectors in the absence of CO2 and Mg2+. This conversion process had the same energy of activation of 95.6kJ/mol both in the presence and in the absence of effectors, whereas the free-energy change value ranged from +2.5kJ/mol to(More)
It has been observed that the procedures of some hospitals do not require any mixing after drugs are added to intravenous bags. Previous studies have shown that mixing often is incomplete in the absence of specific mixing procedures. It has been asserted that mixing is effected by normal handling of bags, and that mixing is sufficient if drug is added to(More)
DNA origami templated self-assembly has shown its potential in creating rationally designed nanophotonic devices in a parallel and repeatable manner. In this investigation, we employ a multiscaffold DNA origami approach to fabricate linear waveguides of 10 nm diameter gold nanoparticles. This approach provides independent control over nanoparticle(More)
