Pseudoazurin binds at a single site on cytochrome c peroxidase from Paracoccus pantotrophus with a K(d) of 16.4 microM at 25 degrees C, pH 6.0, in an endothermic reaction that is driven by a large entropy change. Sedimentation velocity experiments co

Hydrodynamic bead modelling has been widely used in attempts to assess the 3D conformation of proteins in solution. Initially, simple models employing only a small number of beads were used, with a considerable degree of success. Latterly, high-resol

Attempts have been made to correlate estimates of molecular weight for a group of cationic polysaccharides known as chitosans between the highly popular technique of size-exclusion chromatography coupled to multi-angle laser light scattering, "SEC-MA

We have cloned the M and S genes of the restriction-modification (R-M) system AhdI and have purified the resulting methyltransferase to homogeneity. M.AhdI is found to form a 170 kDa tetrameric enzyme having a subunit stoichiometry M2S2 (where the M

To improve the solubilization of two water-soluble xyloglucans, tamarind seed polysaccharide and detarium gum, by reducing substantially molecular aggregation, a "pressure cell" heating method was used. Conditions allowing solubilization and chain de

Six generations of lactodendrimers based on poly(amidoamine) were studied in dilute solutions of 0.2 M NaCl by methods of molecular hydrodynamics (velocity sedimentation and viscometry) and optics (static and dynamic light scattering). Molecular weig

Softening of mango fruit has been investigated by analysis of ripening related changes in the composition of the fruit cell walls. There is an apparent overall loss of galactosyl and deoxyhexosyl residues during ripening, the latter indicating degrad

The molecular weights and gross aqueous solution conformation of two chitosans of different degrees of acetylation, 'Sea Cure +210' (11% acetylated) and KN50 (58% acetylated) were characterized by viscometry, analytical ultracentrifugation and dynami

The utility of using the absorption optical system on an analytical ultracentrifuge for the measurement of molecular weight of a polysaccharide labelled with a suitable chromophore is described. The potential of the method is illustrated, as are the

Dextran is currently being considered as a carrier biopolymer system for drug targeting. Di-iodotyrosine (DIT), and its radioactive derivative are useful markers for identifying the in-vivo route of these substrates. The performance of these substanc
