标题:Chemo-enzymatic synthesis of a c-terminal thioester of an amino acid or a peptide
发明人：QUAEDFLIEG PETER JAN LEONARD MARIO; MERKX NICOLAAS SEBASTIAAN MICHEL
权利人:DSM IP ASSETS BV; QUAEDFLIEG PETER JAN LEONARD M; MERKX NICOLAAS SEBASTIAAN MICH
摘要:The present invention relates to a method for synthesising a C-terminal thioester of an N-protected amino acid or an optionally N-protected oligopeptide, comprising reacting a thiol with a compound selected from optionally N-protected amino acids, amino acid C-terminal esters (other than the ester to be synthesised) and optionally N-protected oligopeptide C-terminal esters (other than the ester to be synthesised) in the presence of a hydrolytic enzyme, thereby forming the thioester.

标题 :Method for producing taurine-enriched milk
发明人：KIM DONG SHIN; PARK DONG JIN
权利人:GYEONG BUK DAEGU DAIRY CO OPER
摘要:The present invention relates to a method for the production of natural taurine-enriched milk using biological metabolism, in which a precursor for synthesis of taurine is prepared in the shape of a pallet or matrix resistant to degradation in the rumen of ruminants and added to a feedstuff, such that biosynthesis of taurine is induced by stimulation of a substrate. According to the method of the present invention, methionine or methionine precursor which is the precursor for taurine synthesis is coated with additives including an inert material and a filler, and thus protected from a rumen pH and an enzymatic action of rumen microorganisms. As a result, problems of the rumen degradation and the metabolism obstruction can be solved. Taurine-enriched milk according to the present invention contains taurine at a higher concentration than general milk, and hence, can be effectively used for the preparation of functional baby foods, and for the preparation of health foods.

标题 :Generation of surface coating diversity
发明人：BARDEN MICHAEL C; KAMBOURIS PETER A
权利人:BARDEN MICHAEL C; KAMBOURIS PETER A; BIO LAYER PTY LTD
摘要:This invention relates to a surface discovery system and high-throughput combinatorial synthesis methods for generating large numbers of diverse surface coatings on solid substrates. The system is built upon a synthon which comprises at least three elements: a chemical backbone coating on the solid substrate that comprises a copolymer (B) of at least one passive constituent (P) and at least one active constituent (A); a spacer unit (S) separating the backbone from a functional group; and a functional group (F). The methods comprise the following steps: 1) selecting a plurality of synthons so that each synthon has at least two points of diversity selected from P, A, S and F; 2) applying copolymer B onto a substrate; and 3) attaching a combination of S and F to constituent A of copolymer B. Steps 2) and 3) are performed such that different synthons are generated on localized regions of the substrate.
