Although, butandiol dehydrogenases are known to play a key role in the production of 2,3-butandiol, their potential as biocatalysts is still not well studied. Here, we investigate the biocatalytic properties of the meso-butanediol dehydrogenase from Bacillus licheniformis DSM 13T (BlBDH). The encoding gene was cloned with an N-terminal StrepII-tag and recombinantly overexpressed in E. coli. BlBDH is highly active towards several non-physiological diketones and α-hydroxyketones with varying aliphatic chain lengths or even containing phenyl moieties. By adjusting the reaction parameters in biotransformations the formation of either the α-hydroxyketone intermediate or the diol can be controlled.}, language = {en} } @article{MuschallikMolinnusJablonskietal.2020, author = {Muschallik, Lukas and Molinnus, Denise and Jablonski, Melanie and Kipp, Carina Ronja and Bongaerts, Johannes and Pohl, Martina and Wagner, Torsten and Sch{\"o}ning, Michael Josef and Selmer, Thorsten and Siegert, Petra}, title = {Synthesis of α-hydroxy ketones and vicinal (R, R)-diols by Bacillus clausii DSM 8716ᵀ butanediol dehydrogenase}, series = {RSC Advances}, volume = {10}, journal = {RSC Advances}, publisher = {Royal Society of Chemistry (RSC)}, address = {Cambridge}, issn = {2046-2069}, doi = {10.1039/D0RA02066D}, pages = {12206 -- 12216}, year = {2020}, abstract = {α-hydroxy ketones (HK) and 1,2-diols are important building blocks for fine chemical synthesis. Here, we describe the R-selective 2,3-butanediol dehydrogenase from B. clausii DSM 8716ᵀ (BcBDH) that belongs to the metal-dependent medium chain dehydrogenases/reductases family (MDR) and catalyzes the selective asymmetric reduction of prochiral 1,2-diketones to the corresponding HK and, in some cases, the reduction of the same to the corresponding 1,2-diols. Aliphatic diketones, like 2,3-pentanedione, 2,3-hexanedione, 5-methyl-2,3-hexanedione, 3,4-hexanedione and 2,3-heptanedione are well transformed. In addition, surprisingly alkyl phenyl dicarbonyls, like 2-hydroxy-1-phenylpropan-1-one and phenylglyoxal are accepted, whereas their derivatives with two phenyl groups are not substrates. Supplementation of Mn²⁺ (1 mM) increases BcBDH's activity in biotransformations. Furthermore, the biocatalytic reduction of 5-methyl-2,3-hexanedione to mainly 5-methyl-3-hydroxy-2-hexanone with only small amounts of 5-methyl-2-hydroxy-3-hexanone within an enzyme membrane reactor is demonstrated.}, language = {en} } @article{JakobMartinezMandaweetal.2013, author = {Jakob, Felix and Martinez, Ronny and Mandawe, John and Hellmuth, Hendrik and Siegert, Petra and Maurer, Karl-Heinz and Schwaneberg, Ulrich}, title = {Surface charge engineering of a Bacillus gibsonii subtilisin protease}, series = {Applied microbiology and biotechnology}, volume = {Vol. 97}, journal = {Applied microbiology and biotechnology}, number = {Iss. 15}, publisher = {Springer}, address = {Berlin}, issn = {1432-0614 (E-Journal); 0171-1741 (Print); 0175-7598 (Print); 0340-2118 (Print)}, pages = {6793 -- 6802}, year = {2013}, language = {en} } @misc{BesslerMaurerMerkeletal.2009, author = {Bessler, Cornelius and Maurer, Karl-Heinz and Merkel, Marion and Siegert, Petra and Wieland, Susanne}, title = {Subtilisin from Bacillus Pumilus and detergent and cleaning agents containing said novel subtilisin [US Patentanmeldung / Internationale Patentanmeldung]}, publisher = {USPTO; WIPO}, address = {Washington; Genf}, pages = {1 -- 39}, year = {2009}, language = {en} } @misc{BesslerMaurerMerkeletal.2007, author = {Bessler, Cornelius and Maurer, Karl-Heinz and Merkel, Marion and Siegert, Petra and Wieland, Susanne}, title = {Subtilisin aus Bacillus pumilus und Wasch- und Reinigungsmittel enthaltend dieses neue Subtilisin [Offenlegungsschrift]}, publisher = {Deutsches Patent- und Markenamt / Europ{\"a}isches Patentamt / WIPO / CIPO}, address = {M{\"u}nchen / Den Hague / Genf}, pages = {1 -- 47}, year = {2007}, language = {de} } @misc{SiegertMerkelHellmuthetal.2012, author = {Siegert, Petra and Merkel, Marion and Hellmuth, Hendrik and O'Connell, Timothy and Maurer, Karl-Heinz}, title = {Stabilisierte fl{\"u}ssige enzymhaltige Tensidzubereitung (Einsatz einer das hydrolytische Enzym stabilisierenden Komponente, die eine Phenylalkyldicarbons{\"a}ure umfasst) [Offenlegungsschrift]}, publisher = {Deutsches Patent- und Markenamt / Europ{\"a}isches Patentamt / WIPO}, address = {M{\"u}nchen / Den Hague / Genf}, pages = {1 -- 15}, year = {2012}, language = {de} } @misc{SiegertMerkelHellmuthetal.2012, author = {Siegert, Petra and Merkel, Marion and Hellmuth, Hendrik and O'Connell, Timothy and Maurer, Karl-Heinz}, title = {Stabilisierte fl{\"u}ssige enzymhaltige Tensidzubereitung (Einsatz einer das hydrolytische Enzym stabilisierende Komponente, die eine Phthaloylglutamins{\"a}ure und/oder eine Phthaloylasparagins{\"a}ure umfasst) [Offenlegungsschrift]}, publisher = {Deutsches Patent- und Markenamt / Europ{\"a}isches Patentamt / WIPO}, address = {M{\"u}nchen / Den Hague / Genf}, pages = {1 -- 16}, year = {2012}, language = {de} } @misc{SiegertMerkelHellmuthetal.2012, author = {Siegert, Petra and Merkel, Marion and Hellmuth, Hendrik and O'Connell, Timothy and Maurer, Karl-Heinz}, title = {Stabilisierte fl{\"u}ssige enzymhaltige Tensidzubereitung (Einsatz einer das hydrolytische Enzym stabilisierende Komponente, die eine Oligoamino-biphenyl-oligocarbons{\"a}ure umfasst) [Offenlegungsschrift]}, publisher = {Deutsches Patent- und Markenamt / Europ{\"a}isches Patentamt / WIPO}, address = {M{\"u}nchen / Den Hague / Genf}, pages = {1 -- 16}, year = {2012}, language = {de} } @misc{SiegertMerkelHellmuthetal.2012, author = {Siegert, Petra and Merkel, Marion and Hellmuth, Hendrik and O'Connell, Timothy and Maurer, Karl-Heinz}, title = {Stabilisierte fl{\"u}ssige enzymhaltige Tensidzubereitung (Einsatz einer das hydrolytische Enzym stabilisierende Komponente, die eine Aminophthals{\"a}ure umfasst) [Offenlegungsschrift]}, publisher = {Deutsches Patent- und Markenamt / Europ{\"a}isches Patentamt / WIPO}, address = {M{\"u}nchen / Den Hague / Genf}, pages = {1 -- 16}, year = {2012}, language = {de} } @misc{SiegertMerkelHellmuthetal.2012, author = {Siegert, Petra and Merkel, Marion and Hellmuth, Hendrik and O'Connell, Timothy and Maurer, Karl-Heinz}, title = {Stabilisierte fl{\"u}ssige enzymhaltige Tensidzubereitung (Einsatz einer das hydrolytische Enzym stabilisierende Komponente, die ein Monosaccharidglycerat umfasst) [Offenlegungsschrift]}, publisher = {Deutsches Patent- und Markenamt / Europ{\"a}isches Patentamt / WIPO}, address = {M{\"u}nchen / Den Hague / Genf}, pages = {1 -- 17}, year = {2012}, language = {de} }
