标题:Quantitative Analysis And Functional Evaluation Of Zinc Ion In The D-Hydantoinase From Pseudomonas Putida Yz-26
摘要:D-Hydantoinase (Hdt) Is A Metal-Dependent Enzyme That Is Widely Used In Industrial Bioconversion To D-Amino Acids As Valuable Intermediates In The Fields Of Food,Pharmaceutical Industry And Agriculture. In This Report,We Prepared Apo-Hdt (Metal-Removed Hdt) And Zn2+-Hdt (Zn2+-Added Hdt) In Vitro From A Recombinant Hdt (Re-Hdt) Expressed In E. Coli. The Zn2+-Hdt And Re-Hdt Contain 2.17 And 0.95 Mol Zn2+ Per Mol Subunit,Respectively,And They Have Comparable Enzymatic Activities. In Contrast,The Apo-Hdt Only Retains 0.04 Mol Zn2+ Per Mol Subunit With Less Than 10% Activity,Compared With The Re-Hdt. When The Apo-Hdt Was Reconstituted With Zncl2,The Enzymatic Activity Recovery Was About 75%. Moreover,The Fluorescence Intensity,Circular Dichroism Spectra And Thermo-Stability Of The Apo-Hdt And Zn2+-Hdt Are Quite Different From Those Of The Re-Hdt. These Data Suggest That The Re-Hdt May Have Two Zn2+-Binding Sites,One Is An Intrinsic Or Tight-Binding Site (Zinc-Alpha) Essential For Its Activity And The Other Is A Vacant Or Loose-Binding Site (Zinc-Beta) Possibly Non-Essential For The Activity.

标题:Synthesis of sarcosinate surfactants
发明人：HEINZMAN STEPHEN WAYNE; DUPONT JEFFREY SCOTT
权利人:PROCTER & GAMBLE
摘要:A method for preparing sarcosinate amido acids and salts thereof of formula (IA) wherein R is a C1 or higher hydrocarbyl substituent, and M is a cationic moiety selected from alkali metal salts and hydrogen, comprising the steps of (a) reacting under anhydrous conditions, in the presence of a base catalyst with basicity equal to or greater than alkoxide catalyst, a carboxylic acid ester of formula (II) with a sarcosine amino acid salt of structure (B) wherein R is as described before, R1 is a C¿1? or higher hydrocarbyl substituent, and M is an alkali metal salt; and (b) optionally, neutralizing the sarcosinate amido acid salt formed by step (a) to form the sarcosinate amido acid, whereby M is hydrogen in formula (IA).

摘要:The present invention is directed to a method for the synthesis of a bi-functional complex comprising a molecule part and an identifier oligonucleotide part identifying the molecule part. A part of the synthesis method according to the present invention is preferably conducted in one or more organic solvents when a nascent bi-functional complex comprising an optionally protected tag or oligonucleotide identifier is linked to a solid support, and another part of the synthesis method is preferably conducted under conditions suitable for enzymatic addition of an oligonucleotide tag to a nascent bi-functional complex in solution.
