WebA cDNA for potato (Solanum tuberosum L.) 3-deoxy-D-arabino-heptulosonate 7-phosphate synthase, the first enzyme of the shikimate pathway, encodes a 56 KD polypeptide whose amino terminus resembles a chloroplast transit sequence. The cDNA was placed downstream of th WebDec 31, 1997 · Of the two nonhomologous DAHP synthase families known, the N. gonorrhoeae protein belongs to the family I assemblage. KDOP synthase exhibited an ability to replace arabinose-5-P with either erythrose-4-P or ribose-5-P as alternative substrates. The results of periodate oxidation studies suggested that the product formed …

WebJan 22, 2003 · The DAHP synthase isoenzymes of yeast as well as E. coli represent such extended β/α barrels with the catalytic site on the C-terminal face, as it is in all β/α barrels. In these enzymes, extensions are used to construct a cavity on the N-terminal side of the barrel that possibly facilitates binding of effector molecules. 3-Deoxy-D-arabinoheptulosonate 7-phosphate (DAHP) synthase (EC 2.5.1.54) is the first enzyme in a series of metabolic reactions known as the shikimate pathway, which is responsible for the biosynthesis of the amino acids phenylalanine, tyrosine, and tryptophan. Since it is the first enzyme in the shikimate pathway, it … See more This enzyme belongs to the family of transferases, to be specific those transferring aryl or alkyl groups other than methyl groups.
