The interactions between pig heart citrate synthase and mitochondrial malate dehydrogenase or cytosolic malate dehydrogenase were studied using the frontal analysis method of gel filtration and by precipitation in polyethylene glycol. This method showed that an interaction between citrate synthase and mitochondrial malate dehydrogenase occurred but no interaction between citrate synthase and cy...

Cholinesterases are efficient scavengers of organophosphates and are currently being developed as drugs for treatment against poisoning by such compounds. Recombinant ChE bioscavengers have very short circular longevity, a limitation that can be overcome by complex post-translation manipulations or by chemical modification such as polyethylene glycol conjugation. Series of multiple Lys-Ala muta...

Although low concentrations of polyethylene glycol (1-5%, w/v) are essential for growing crystals of phosphoglucomutase from ammonium sulfate solutions (at close to 50% of saturation), the observed rate constant for short-term crystal growth on a defined, microcrystalline surface is essentially independent of polyethylene glycol concentration under these conditions. But this cosolute produces a...

Essential oils (EOs) are technological options that may be employed in natural foods due to their antimicrobial activities. However, restrictions exist when high EOs concentrations are required which, in their turn, affect sensory qualities. Technological alternatives, such as combination of EOs with chelating and dispersing agents, have been proposed in the literature. Current research determi...
