Fermentative production of ophthalmic acid
Research aims Escherichia coli YggS is a highly conserved pyridoxal phosphate (PLP)-binding protein whose biochemical function is unknown. We found that a yggS-deficient E. coli s t ra in (ΔyggS ) accumulates an unusual metabol i te , ophthalmic ac id (γ-L-glutamyl-L-2-aminobutyryl-glycine, Fig. 1). This ∆yggS mutant is the first microorganism that accumulates high levels of ophthalmic acid. Op...
متن کاملFermentative butanol production by Clostridia.
Butanol is an aliphatic saturated alcohol having the molecular formula of C(4)H(9)OH. Butanol can be used as an intermediate in chemical synthesis and as a solvent for a wide variety of chemical and textile industry applications. Moreover, butanol has been considered as a potential fuel or fuel additive. Biological production of butanol (with acetone and ethanol) was one of the largest industri...
متن کاملFermentative production of L-alanyl-L-glutamine by a metabolically engineered Escherichia coli strain expressing L-amino acid alpha-ligase.
In spite of its clinical and nutritional importance, l-alanyl-l-glutamine (Ala-Gln) has not been widely used due to the absence of an efficient manufacturing method. Here, we present a novel method for the fermentative production of Ala-Gln using an Escherichia coli strain expressing l-amino acid alpha-ligase (Lal), which catalyzes the formation of dipeptides by combining two amino acids in an ...
متن کاملFermentative production of butanol--the industrial perspective.
A sustainable bacterial fermentation route to produce biobutanol is poised for re-commercialization. Today, biobutanol can compete with synthetic butanol in the chemical market. Biobutanol is also a superior biofuel and, in longer term, can make an important contribution towards the demand for next generation biofuels. There is scope to improve the conventional fermentation process with solvent...
متن کامل2-Fluoro-l-histidine
The title compound, C(6)H(8)FN(3)O(2), an analog of histidine, shows a reduced side-chain pK(a) (ca 1). The title structure exhibits a shortening of the bond between the proximal ring N atom and the F-substituted ring C atom, indicating an increase in π-bond character due to an inductive effect of fluorine.
