The present invention relates to an improved biocatalytic process for producing vanillin from ferulic acid based on a genetically engineeredstrains, as well as to saidstrains.

[object Object]

The present invention relates to the production of heterologous polypeptides in a recombinant bacterial host cell, wherein the bacterial host cell is rendered unable to deactivate the promoter controlling the expression of the heterologous polypeptide in the absence of an inducer.

Regulation of inducible promoters

The present invention relates to the production of heterologous polypeptides in a recombinant bacterial host cell, wherein the bacterial host cell is rendered inable to deactivate the promoter controlling the expression of the heterologous polypeptide in the absence of an inducer.

The present invention relates to a vector expressible in a prokaryotic host and a nucleic acid sequence comprising a mannose-inducible promoter of the mannose operon ofwherein the vector and nucleic acid sequence, respectively, can be suitably used for transforming a host cell for expression of a heterologous nucleic acid sequence coding a polypeptide in, in particular, high cell density fermentation.

Vector comprising mannose promoter and mannose promoter

The present invention relates to a process for preparing, in particular, enantiomerically enriched L-&#x3b1;-amino acids, in particular those of the general formula (I). In this connection, the process according to the invention uses 2-ketocarboxylic acids which are converted into the desired products using a whole-cell catalyst which comprises an amino acid dehydrogenase and a cofactor-regenerating enzyme. 

Process for preparing optically active amino acids using a whole-cell catalyst

A novel rec-L-N-carbamoylase fromand its method of use for producing L-amino acids. The recombinantly produced L-carbamoylase is unexpectedly stable, so that an industrial method of producing L-amino acids can be established with it, in contrast to previously known L-carbamoylases.

Recombinant L-N-carbamoylase from Arthrobacter aurescens and method of producing L-amino acids therewith

The present invention relates to a new D-carbamoylase and the gene sequences which code for this from the organism DSM 20117. Plasmids, vectors, microorganisms, particular primers and specific possible uses of the enzymes according to the invention are also mentioned. The invention moreover describes a new process for the discovery of enzymes which can be employed in a process for the preparation of D-amino acids starting from 5&prime;-substituted hydantoins.

Arthrobacter D-carbamoylase and methods of preparing enantiomerically enriched D-amino acids

A microorganism is described which is transformed with DNAs which encode a hydantoinnase, a racemase, and a carbamoylase. As a result, the microorganism is able to degrade hydantoins directly to amino acids. A process for the production of the microorganism and a process for producing amino acids with the microorganism is also described.
