摘要:
A process is provided of conjugating a recognition element such as a biomolecule to a hydrophobic multifunctional linker molecule by incorporating a multifunctional linker molecule including one or more anchoring groups, a reporter group and a reactive site thereon into a membrane, and, reacting the membrane including the incorporated multifunctional linker molecule with a pre-selected recognition element to form a covalently bound recognition element-multifunctional linker molecule-membrane assembly. Also, a chemical assembly suitable for subsequent covalent attachment of a recognition element is provided such assembly including a multifunctional linker molecule including one or more anchoring groups, a reporter group, and a hydrophilic spacer terminated by a reactive group capable of subsequent covalent bonding, the one or more anchoring groups incorporated in a membrane.

摘要:
A method of removing heavy metals from aqueous solution, a composition of matter used in effecting said removal, and apparatus used in effecting said removal. One or more of the polypeptides, poly (.gamma.-glutamylcysteinyl)glycines, is immobilized on an inert material in particulate form. Upon contact with an aqueous solution containing heavy metals, the polypeptides sequester the metals, removing them from the solution. There is selectivity of poly (.gamma.-glutamylcysteinyl)glycines having a particular number of monomer repeat unit for particular metals. The polypeptides are easily regenerated by contact with a small amount of an organic acid, so that they can be used again to remove heayv metals from solution. This also results in the removal of the metals from the column in a concentrated form.
摘要:
The reactivity of given metabolites is assessed using selected empirical atomic properties in the potential reaction center. Metabolic reactions are represented as biotransformation rules. These rules are generalized from the patterns in reactions. These patterns are not unique to reactants but are widely distributed among metabolites. Using a metabolite database, potential substructures are identified in the metabolites for a given biotransformation. These substructures are divided into reactants or non-reactants, depending on whether they participate in the biotransformation or not. Each potential substructure is then modeled using descriptors of the topological and electronic properties of atoms in the potential reaction center; molecular properties can also be used. A Support Vector Machine (SVM) or classifier is trained to classify a potential reactant as a true or false reactant using these properties.
