New drugs are needed to assure effective therapies for previously untreated diseases, emerging diseases, and personalized medicine, but the process of drug development is complex, costly, and time-consuming. This is especially problematic considering that ...
Previous retrosynthetic and isotope-labeling studies have indicated that biosynthesis of the iron guanylylpyridinol (FeGP) cofactor of [Fe]-hydrogenase requires a methyltransferase. This hypothetical enzyme covalently attaches the methyl group at the 3-pos ...
Enzymes have evolved during millions of years to become efficient catalysts for specific biochemical reactions within a specific range of working conditions in the cellular environment. The activity of an enzyme is directly related to its folded structure ...
The activity of penicillin acylase has been studied in aq. and org. solvents, as free enzyme as well as immobilized within the membrane of liq.-core capsules. The activity of the enzyme is inhibited by the accumulation of the products of the hydrolysis rea ...
