Synthesis of N-acetylneuraminic acid and of CMP-N-acetylneuraminic acid in the rat liver cell.
Adult male rats, under starving and normal conditions, were injected intravenously with N-acetyl[3H]mannosamine and after various time intervals the specific radioactivities of free N-acetylneuraminic acid (NeuAc) and CMP-N-acetylneuraminic acid were determined in the liver. The specific radioactivity of free NeuAc was high even within 20s after injection; the maximum was reached between 7 and ...
متن کاملCorrigendum: Characterization of a novel N-acetylneuraminic acid lyase favoring industrial N-acetylneuraminic acid synthesis process
The original version of this article contained an error in testing the kinetic parameters of CgNal towards pyruvate, in which the concentration of ManNAc (50 mM) was not in excess. This error was corrected by re-running the assay in the presence of excessive ManNAc (180 mM). The corrected kinetic parameters of CgNal towards pyruvate are shown in Table 1. These changes do not change the conclusi...
متن کاملCharacterization of a novel N-acetylneuraminic acid lyase favoring N-acetylneuraminic acid synthesis
N-Acetylneuraminic acid lyase (NAL, E.C. number 4.1.3.3) is a Class I aldolase that catalyzes the reversible aldol cleavage of N-acetylneuraminic acid (Neu5Ac) from pyruvate and N-acetyl-D-mannosamine (ManNAc). Due to the equilibrium favoring Neu5Ac cleavage, the enzyme catalyzes the rate-limiting step of two biocatalytic reactions producing Neu5Ac in industry. We report the biochemical charact...
متن کاملCrystal structure of 2-[N-(t-butoxycarbonyl)amino]-4-(thymin-1-yl)-butyric acid methyl ester.
psuedopeptide backbone composed of N-(2-aminoethyl) glycine units, and nucleobases are attached by methylene carbonyl linkers (Fig. 1). Since the binding of PNA to DNA inhibits transcription, the potential of PNA has been focused to target an antisense drug.1 Moreover, PNA-peptides hybridization and improvements of the PNA backbone unit were developed to form DNA-DNA-PNA triplexes with nonspeci...
