Abstract:
The present invention relates to novel mutants with cyclase activity and use thereof in a method for biocatalytic cyclization of terpenes, such as in particular for the production of isopulegol by cyclization of citronellal; a method for the preparation of menthol and methods for the biocatalytic conversion of further compounds with structural motifs similar to terpene.
Abstract:
The present invention relates to a method for the enzymatic decarboxylation of malonic acid (propanedioic acid) derivatives catalyzed by enzymes structurally and/or functionally related to arylmalonate decarboxylase (AMDase) as isolated from microorganisms of the genus Bordetella. The present invention also relates to novel enzymes with a decarboxylase activity, useful for performing the claimed method, mutants thereof, corresponding coding sequences and expression systems, methods of preparing said novel enzymes, and screening methods for obtaining further suitable enzymes also having said decarboxylase activity.
Abstract:
Provided herein are oral care compositions comprising HABP, which are useful in methods of repairing or inhibiting dental erosion, promoting dental remineralization, and/or enhancing the anti-cavity effects of fluoride.
Abstract:
The invention relates to a method for the enzyme-catalysed hydrolysis of polyacrylic acid esters. According to the method, at least one polyacrylic acid ester is provided and incubated with at least one enzyme selected from enzymes (EC 3.1) acting on ester bindings, until the ester groups contained in the polyacrylic acid ester are partially or fully hydrolytically split, and optionally the modified polymer obtained thereby is isolated. The invention also relates to the enzymes used and mutants thereof, nucleic acids coding for the enzymes, vectors comprising the nucleic acids, micro-organisms comprising the vectors, and the use of the enzymes, the vectors or the micro-organisms for carrying out a method for the enzyme-catalysed hydrolysis of polyacrylic acid esters. The present application also relates to polymer reaction products that can be obtained by the method, and methods for producing esterases.
Abstract:
Process for producing optically active 3-aminocarboxylic acid ester compounds of general Formula I, and the ammonium salts thereof, in which R1 stands for alkyl, alkoxyalkyl, alkenyl, cycloalkyl, heterocycloalkyl, aryl, or hetaryl, and R2 stands for alkyl, cycloalkyl or aryl, in which an enantiomeric mixture of a simply N-acylated 3-aminocarboxylic acid ester of general formula (I.b), in which R1 and R2 have the meanings given above and R3 stands for hydrogen, alkyl, cycloalkyl or aryl, is submitted to an enantioselective deacylation by adding a polypeptide according to claim 1.
Abstract:
A process for preparing linear or branched primary alcohols with 3 to 13 carbon atoms from linear or branched alkanes with 3 to 13 carbon atoms by incubating a host organism having a functional P153 enzyme under elevated pressure in the presence of oxygen.
