Disease relevance of tktA

The 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 [1].

High impact information on tktA

Meanwhile, the amplified tktA gene significantly increased both PHB biosynthesis and cell growth as a result of the effective flow of glyceraldehyde-3-phosphate into acetyl-CoA along with the concomitant supplementation of NADPH [2].
