Enzymatic Sulfurylation Mechanisms
<p>Sulfate activation and transfer to lipids, polysaccharides, and aminoalkyl phenols have been studied In a variety of biological systems. The transfer of S<sup>35</sup>O<sub>4</sub> from radioactive 3'-phosphoadenoslne 5'-phosphosulfate (PAPS<sup>35</sup>) into lipid-soluble material has been …

Enzymatic acylation of starch
… where the starch is gelatinised prior to enzymatic reaction. The reaction showed a pronounced optimal water content (1.25 mL of water for gelatinisation per g of starch), in which the equilibrium was sufficiently shifted, in order to produce starch acylated to a useful extent (0.018 DS). …

Enzymatic degradation of egg yolk cholesterol
A rapid, reliable and accurate gas chromatographic method for the determination cholesterol in egg yolk and processed foods was developed from a method of Kovacs (1990). A sample is heated in a sealed tube with a solution of potassium hydroxide in ethanol containing the internal standard, …

The dynamics of enzymatic switch cascades
… protein kinase (MAPK) multi-step enzymatic switching cascade, a highly conserved architecture utilised in cellular signal transduction. In treating the equations of motion, we replace the usual deterministic differential equation formalism with stochastic equations to accurately …

The enzymatic solubilization of crystalline cellulose
A crude cellulolytic enzyme prepq.ration derived from Trichoderma viride was capable of solubilizing native crystalline forms of cellulose. Enzyme activity ("hydrocellulase") was determined by measuring the decrease in turbidity of the assay reaction mixture which contained a suspended …

Enzymatic removal of dung from cattle hides
One of the major problems facing the meat and leather industries is dung cladding on hides. Dung dried onto hides is difficult to remove during the early stages of processing, resulting in the necessity for prolonging the soaking step, with the consequence of risking bacterial damage to the hides. …

Enzymatic Polymerization of High Molecular Weight DNA
… 150 nucleotides. In contrast, polymerase based enzymatic synthesis methods (e.g., polymerase chain reaction) are not limited by product length, but require a DNA template to guide the synthesis. Furthermore, advanced DNA bionanotechnology requires tailorable structural and self-assembly …

Enzymatic production of oligosaccharides in centrifugal fields
The aims of this work have been to identify an enzymatic reaction system suitable to investigate and develop the high-speed centrifuge as a novel reaction system for performing such reactions. The production of galacto-oligosaccharides by the trans-galactosyl activity of the enzyme β-galactosidase …

Conserved Conformational Dynamics Control PTP1B Enzymatic Activity
The long-accepted paradigm of biochemistry is that enzyme function depends on the three-dimensional (3D) structure. However, this paradigm is changing. Namely, the emerging view is that protein function also depends on intrinsic protein dynamics. Further, while sequence conservation is …

Small Molecule Modulation of Caspase Enzymatic Activity
… activator, PAC-1, was conducted. Through enzymatic assays under various buffer conditions, the in vitro mechanism of PAC-1 activation of procaspase-3 was conclusively found to be through relief of enzyme inhibition by metal ions. Zinc, the most physiologically relevant metal inhibitor, was …
