Myoglobin from the dark muscle of sardine (Sardinella gibbosa) with the molecular weight of 15.3 kDa was isolated and characterized. The different myoglobin derivatives exhibited varying thermal unfolding characteristics. Deoxymyoglobin showed a single distinct endothermic peak at 74.5°C, whereas two transition temperatures were noticeable for oxymyoglobin (64.5°C and 78.4°C) and metmyoglobin (...

The purpose of present article is to examine the peristaltic flow of Jeffrey fluid in a curved channel. An electrically conducting fluid in the presence of radial applied magnetic field is considered. Analysis of heat and mass transfer is carried out. More generalized realistic constraints namely the convective conditions are utilized. Soret and Dufour effects are retained. Problems formulation...

Placing a fluid mixture in temperature gradient can cause concentration gradients to build up, phenomenon called the Soret effect. The authors simulate this effect for of monomers and dimers, find contribution from internal degrees freedom dimers. Under some conditions sign is reversed.

We consider a long-wave oscillatory Marangoni convection in a layer of a binary liquid in the presence of the Soret effect. A weakly nonlinear analysis is carried out on a hexagonal lattice. It is shown that the derived set of cubic amplitude equations is degenerate. A three-parameter family of asynchronous hexagons (AH), representing a superposition of three standing waves with the amplitudes ...

A haemoprotein was purified to apparent homogeneity from Bengal-gram seeds. The purified protein exhibited an absorption maximum at 412 nm (Soret band) that upon reduction with dithionite gave rise to a shift in the Soret band to 426 nm with concomitant appearance of an alpha-band at 559 nm and a beta-band at 530 nm. In the reduced state the Bengal-gram haemoprotein showed reactivity towards CO...

We are investigating the redox chemistry of wild-type (WT) and mutant (1-12G) cytochrome P450 BM3. Absorption spectra in solution feature the Fe(III) Soret at 418 nm for WT and a split Soret for 1-12G at 390 and 418 nm. Voltammetry of the proteins within DDAPSS films on the surface of carbon electrodes reveal nearly identical Fe(III/II) potentials (approximately -200 mV vs Ag/AgCl), but signifi...

In this paper an exact analysis to study the combined effects of thermal diffusion (Soret) and heat generation on a mixed convection flow past an infinite vertical porous plate in presence of thermal radiation has been made. The governing system of partial differential equations subject to favorable boundary conditions is being solved analytically. Cogly-Vincentine-Gilles equilibrium approximat...

The globins from sperm whale and from Aplysia limacina myoglobins were reconstituted by addition of stoichiometric ferric protohaem and the Soret c.d. was followed as a function of time. For both reconstituted proteins, the Soret c.d. changes with time, reflecting haem reorientation inside its pocket, as previously described [Aojula, Wilson & Drake (1986) Biochem. J. 237, 613-616] for sperm wha...
