  • Publication number: 20080311631
    Abstract: The invention relates to a process for the biosynthetic production of 4-amino-4-deoxychorismate (ADC) performed fermentatively in vivo with a 4-amino-4-deoxychorismate synthase, preferably a PabAB bipartite protein (which may be a fusion protein), at an increased level of activity, thereby obtaining a broth comprising ADC and 4-amino-4-deoxyprephenate (ADP), that are recovered. The invention also relates to a further process of converting the ADP into p-aminophenylalanine. The invention, moreover relates to biosynthetic production of [3R,4R]-4-amino-3-hydroxycyclohexa-1,5-diene-1-carboxylic acid (3,4-CHA), by concerted action of such 4-amino-4-deoxychorismate synthase and of an enzyme capable of converting isochorismate into [5S,6S]-5,6 dihydroxycyclohexa-1,3-diene-1-carboxylic acid (2,3-CHD), preferably a phenazine biosynthesis protein PhzD, including recovery of 3,4-CHA. The invention also relates to expression vectors and host cells for use in any of such processes.

  • Publication number: 20060234358
    Abstract: A process for the microbial production of aromatic amino acids and other metabolites of the aromatic amino acid biosynthetic pathway The invention relates to a process for the microbial production of aromatic amino acids and other metabolites of the aromatic amino acid biosynthetic pathway. Microbially produced substances such as fine chemicals, in particular aromatic amino acids or metabolites of the aromatics biosynthetic pathway, are of great economic interest, and the need for amino acids, for example, continues to increase. The inventors found that, after introducing a pyc gene sequence into microorganisms, it was possible to produce aromatic amino acids and also metabolites of the aromatic biosynthetic pathway in an improved manner. The process of the invention is particularly suitable for producing L-phenylalanine.

  • Publication number: 20050227333
    Abstract: The invention relates to a process for the production of an aromatic amino acid metabolite or derivative thereof by aerobic fermentation of Escherichia coli, which fermentation comprises a growth and a production phase and in which fermentation glucose and L-tyrosine are controlled, wherein during at least part of the production phase, the glucose concentration in the fermentation medium is controlled within the range of 1-20 g/L and the L-tyrosine concentration in the fermentation medium is controlled below 36 mg/L.

  • Publication number: 20030224495
    Abstract: In the production of genetically-modified, non-pathogenic organisms particularly an improved production and isolation of trans-dihydroxycyclohexadiene carboxylic acids and/or derivatives thereof, the synthesis of the transhydroxy cyclohexadiene carboxylic acids is performed in an enantiomer-pure form without detectable impurities with chorismate by cultivation of at least one genetically altered non-pathogenic organism which has an aromate embolism and has, in comparison with a corresponding, genetically not altered organism, an increased activity of the isochorismate synthase (EntC) and isochorismatase (EntB) and an activity of the 2,3 dihydroxybenzoate synthase (EntA) which is close to zero, or an increased activity of the isochorismatase (EntB) and a reduced activity of the isochorismate synthase (EntC) and an activity of the 2,3-dihydroxybenzoat-synthase (entA) of close to zero.

  • Patent number: 6316232
    Abstract: The invention makes available, by means of an increased provision of intracellular metabolic intermediates, in particular of erythrose 4-phosphate, alternative processes for the microbial preparation of substances, in particular of aromatic amino acids such as L-phenylalanine, in which processes the activity of a transaldolase is increased in a microorganism producing these substances. In preferred embodiments of the invention, the activity of a transketolase or the activity of a transport protein for the PEP-independent uptake of a sugar and/or the activity of a kinase which phosporylates the relevant sugar are/is additionally increased. The invention also relates to gene structures, and to transformed cells carrying these gene structures, which make it possible to implement these processes in a particularly successful manner.

  • Patent number: 4802059
    Abstract: In a low-voltage circuit breaker, terminal points for connecting contact arrangements to stationary bus bars are provided. Between the terminal points and the stationary bus bars, connecting bars are arranged which are braced relative to the housing of the circuit breaker by support bodies against current forces. The support bodies are parts comprising relatively thin insulating material with cutouts for the connecting bars. Detent projections allow the support bodies to snap into corresponding recesses in the lateral housing walls of the circuit breaker.
