Autor: Doreen Lisicki, Jürgen Hensel, Dieter Frense, Martin Becker, Till Hornbogen, Christian Pflieger, Rainer Zocher, Gerald Prof. Dr. Lauckner, Dieter Beckmann
Publikováno v: Chemie Ingenieur Technik. 78:120-123
Den vorgestellten Arbeiten liegt die Idee zugrunde, mit Hilfe einer Acetyltransferase, die kurzlich aus Taxus baccata isoliert werden konnte, Baccatin III kontinuierlich in einem Enzymreaktor herzustellen. Substrat der enzymatischen Umsatzreaktion is

Publikováno v: The Journal of Antibiotics. 54:797-804
New cyclohexadepsipeptides of the enniatin type with potential anthelmintic properties were produced by two different strategies: 1. In vitro synthesis by use of the multienzyme enniatin synthetase, and 2. in vivo precursor feeding of enniatin produc

Biosynthesis of PF1022A and Related Cyclooctadepsipeptides
Autor: Wolfram Weckwerth, Koichi Miyamoto, Katsuhura Iinuma, Martin Krause, Mirko Glinski, Thomas Storm, Gerd Bonse, Horst Kleinkauf, Rainer Zocher
Publikováno v: Journal of Biological Chemistry. 275:17909-17915
PF1022A belongs to a recently identified class of N-methylated cyclooctadepsipeptides (CODPs) with strong anthelmintic properties. Described here is the cell-free synthesis of this CODP and related structures, as well as the purification and enzymati

Biosynthesis of Taxol: Enzymatic Acetylation of 10-Deacetylbaccatin-III to Baccatin-III in Crude Extracts from Roots ofTaxus baccata
Autor: Bettina Kammer, Christine Hacker, Till Hornbogen, Wolfram Weckwerth, Dietrich Ewald, Rainer Zocher
Publikováno v: Biochemical and Biophysical Research Communications. 229:16-20
The biosynthesis of taxol is a multistep process. One intermediate reaction is the acetylation of 10-deacetylbaccatin-III (10-DAB) to baccatin-III, an assumed precursor of taxol. Here we describe the cell free acetylation of 10-DAB in crude extracts

Enniatin production by fusarium strains and its effect on potato tuber tissue
Autor: Matthias Herrmann, Andangela Haese, Rainer Zocher
Publikováno v: Applied and Environmental Microbiology. 62:393-398
Several Fusarium strains produce the cyclohexadepsipeptide enniatin, a host-nonspecific phytotoxin. Enniatins are synthesized by the 347-kDa multifunctional enzyme enniatin synthetase. In the present study, 36 Fusarium strains derived from a wide ran

Bacterial Expression of Catalytically Active Fragments of the Multifunctional Enzyme Enniatin Synthetase
Autor: Rainer Zocher, Tatjana von Ostrowski, Rembert Pieper, Angela Haese
Publikováno v: Journal of Molecular Biology. 243:116-122
Enniatin synthetase catalyzes the biosynthesis of N-methylated cyclohexadepsipeptides. The 347 kDa enzyme is encoded by the esyn1 gene of Fusarium scirpi and contains two domains (EA and EB) homologous to each other and to regions of other microbial

Purification and characterization of eucaryotic alanine racemase acting as key enzyme in cyclosporin biosynthesis
Autor: Rainer Zocher, Horst Kleinkauf, E Schneider-Scherzer, Kai Hoffmann
Publikováno v: Journal of Biological Chemistry. 269:12710-12714
A specific alanine racemase, which is a key enzyme in the biosynthesis of the undecapeptide cyclosporin A, was purified to electrophoretic homogeneity from the fungus Tolypocladium niveum. This is the first enzyme of this kind isolated from a eucaryo
