摘要： The present invention relates to glutamate dehydrogenase mutants and their application in preparation of L-phosphinothricin. The amino acid sequences of the glutamate dehydrogenase mutants are as shown in SEQ ID NO. 1-9, 11, 13, 15, 17-19 and 22. By means of molecular engineering, mutating the specific alanine in glutamate dehydrogenase substrate-binding pocket into glycine and/or mutating the specific valine in glutamate dehydrogenase substrate-binding pocket into alanine, the present invention has obtained NADPH-specific glutamate dehydrogenase mutants with high enzyme activity in catalyzing the substrate 2-oxo-4-[(hydroxy)(methyl)phosphinoyl]butyric acid or its salt for L-phosphinothricin preparation or NADH-specific glutamate dehydrogenase mutants with catalytic activity toward PPO; this has significantly improved substrate conversion, and increased the product concentration of the L-phosphinothricin preparation process.

摘要： Healthcare costs are a significant worldwide, with many patients being denied medications because of their high prices. One approach to addressing this problem involves the biosynthesis of chiral drug intermediates, an environmentally friendly solution that can be used to generate pharmaceuticals at much lower costs than conventional techniques. In this context, embodiments of the invention comprise methods and materials designed to allow microorganisms to biosynthesize the nonnatural amino acid L-homoalanine. As is known in the art, L-homoalanine is a chiral precursor of a variety of pharmaceutically valuable compounds including the anticonvulsant medications levetiracetam (sold under the trade name Keppra®) and brivaracetam, as well as ethambutol, a bacteriostatic antimycobacterial drug used to treat tuberculosis. Consequently, embodiments of the invention can be used in low cost, environmentally friendly processes to generate these and other valuable compounds.

摘要： The invention relates to promoters of the genes glutamate dehydrogenase, &bgr;-acetylhexosaminidase and &ggr;-actin and their use in systems of expression, secretion and anti-sense of filamentary fungi. The invention also relates to the use of the promoters of the genes which code: (I) glutamate dehydrogenase NADP depending (EC.1.4.1.4) of Penicillium chrysogenum, (II) &ggr;-N-actylhexosaminidase (EC.3.2.1.52) of Penicillium chrysogenum and (III) &ggr;-actin of Penicillium chrysogenum and Acrimonium chrysogenum, which can be used for the construction of potent vectors of expression and secretion useful both for P. chrysogenum and for A. chrysogenum and related species. These promoters can also be used for blocking the genic expression through anti-sense construction. Under the control of the above mentioned promoters, it is possible to conduct the expression of other genes in filamentary fungi, thereby increasing the production of antibiotics and/or proteins inherent to the same.
