Phosphoenolpyruvate Availability and the Biosynthesis of Shikimic Acid
Biotechnology Progress, 2003The impact of increased availability of phosphoenolpyruvate during shikimic acid biosynthesis has been examined in Escherichia coli K-12 constructs carrying plasmid-localized aroF(FBR) and tktA inserts encoding, respectively, feedback-insensitive 3-deoxy-d-arabino-heptulosonic acid 7-phosphate synthase and transketolase.

Evaluation of shikimic acid as a precursor of pyocyanine
Canadian Journal of Microbiology, 1969The availability of a new resuspension medium and the isolation of a strain of Pseudomonas aeruginosa unable to use quinic acid for growth have facilitated the evaluation of shikimic and quinic acids as precursors of pyocyanine. Shikimic acid or its derivatives were shown to account for virtually 100% of the carbon atoms of the phenazine nucleus of ...

Helvetica Chimica Acta, 1992
AbstractQuinic acid (1a), shikimic acid (2), and their derivatives were acylated in organic solvents by several lipases and by the protease subtilisin Carlsberg. The most satisfactory results were obtained with methyl (or benzyl) quinate (7a (or 8a)) and lipase from Chromobacterium viscosum adsorbed on Celite, which showed an overshelming preference ...

Colorimetric assay of shikimic acid against quinic acid
Analytical Biochemistry, 1972Abstract Shikimic acid heated with p-hydroxybenzaldehyde and concentrated sulfuric acid produces an intense and stable purple-violet dye with absorption maximum at 590 nm, and can be quantitatively determined in the range from 15 to over 120 ng (0.1 to 0.7 μmole/ml). Under the same conditions quinic acid produces no color reaction. Shikimic acid can

Interaction of shikimic acid with shikimate kinase.
Biochemical and biophysical research communications, 2005The crystal structure of shikimate kinase from Mycobacterium tuberculosis (MtSK) complexed with MgADP and shikimic acid (shikimate) has been determined at 2.3A resolution, clearly revealing the amino acid residues involved in shikimate binding. In MtSK, the Glu61 strictly conserved in SK forms a hydrogen bond and salt-bridge with Arg58 and assists in ...

A microcolorimetric method for the determination of shikimic acid
Archives of Biochemistry and Biophysics, 1957Abstract 1. 1. A spectrophotometric determination of shikimic acid, based on the reaction of the periodate oxidation product of shikimic acid with aniline to yield a Schiff's base, is described. 2. 2. Sugars, amino acids, and other organic acid so far tested give no color reaction in the procedure concerned. 3. 3.

Communications in Soil Science and Plant Analysis, 2001
An uncomplicated, benign-by-design analytical method for the determination of shikimic acid in plant tissue was developed. The method is simple and automated entailing a water extraction followed by liquid chromatographic analyses. Use of reagents, solvents and generation of waste are minimized, and the use of toxic/hazardous reagents is eliminated as ...

Preparation of a fluorinated shikimic acid
Journal of Fluorine Chemistry, 1994Abstract The reaction of dialkylaminosulfur trifluoride with shikimic acid (1) gives a single isomer of a product 2 in which two hydroxy groups have been replaced by fluorine.

Shikimic Acid Pathway: Phenols
2023Plant metabolites having one or more hydroxyl groups attached to an aromatic ring are known as phenols. Phenols are a heterogeneous group of compounds. One of the most important functions of phenols is in plant communication e.g., allelopathy, attracting pollinating and disseminating agents, attracting symbiotic bacteria, and inhibiting pathogens and ...
