Modification of collagen film by certain chemical agents.
Morphological changes and the content of free carboxyl groups in bovine collagen (type I) film under the influence of trypsin, hydrochloric acid (HCl) and ethylenediaminetetraacetic acid (EDTA) were studied. Incubation with trypsin and HCl was found to cause some delamination of the film and the appearance of some low-density spots. Incubation with EDTA did not cause any morphological changes. ...
متن کاملChemical modification of the active site sulfhydryl group of saccharopine dehydrogenase (L-lysine-forming).
Saccharopine dehydrogenase (e-N-(L-glutaryl-2)-L1ysine:NAD oxidoreductase (L-lysine-forming) EC 1.5.1.7) is inhibited by a variety of sulfhydryl reagents. Althoughp-chloromercuribenzoate and 5,5’-dithiobis(2nitrobenzoate) react with three sulfhydryl groups present in the enzyme, reaction with one reactive sulfhydryl group leads to complete loss of catalytic activity. Amino acid analysis of the ...
متن کاملEffect of a Clathrate-Forming Counterion on Micellar Solubilization
Clathrate hydrates are supramolecular solids in which small, hydrophobic species are trapped inside a network of hydrogen-bonded water cages. While the best known examples are the natural gas hydrates, similar crystalline structures can also be formed from salts of tetra-n-butylammonium hydroxide (TBAOH). When TBAOH is reacted with medium to long chain carboxylic acids it produces surfactant co...
متن کاملChemical modification of triplex-forming oligonucleotide to promote pyrimidine motif triplex formation at physiological pH.
Extreme instability of pyrimidine motif triplex DNA at physiological pH severely limits its use in wide variety of potential applications, such as artificial regulation of gene expression, mapping of genomic DNA, and gene-targeted mutagenesis in vivo. Stabilization of pyrimidine motif triplex at physiological pH is, therefore, crucial for improving its potential in various triplex-formation-bas...
متن کاملChemical modification of biocatalysts.
Although several powerful methods exist for the redesign of enzyme structure and function these are typically limited to the 20 most abundant proteinogenic amino acids. The use of chemical modification overcomes this limitation to allow virtually unlimited alteration of amino acid sidechain structures. If heterogeneous mixtures of enzyme products are to be avoided, however, the required chemist...
