Studies with extracts obtained from mung beans (Phaseolus aureus) showed that UDP-N-acetyl d-glucosamine is formed from d-fructose 6-phosphate by a series of the following enzymic reactions: [Formula: see text]UDP-N-acetyl-d-glucosamine inhibits the first reaction in the multistep pathway leading to its biosynthesis.

Ofloxacin is an important drug with anti-bacterial effects, and (–)-ofloxacin has been shown to have better activity than racemic ofloxacin. But the chiral resolution of compounds a major challenge worldwide. Many methods do not show high specificity target molecules, causing errors in separation these pharmaceutical thus affecting purity drugs. The paper mainly researches on method for quick o...

the first enzyme of the pathway for uridine diphosphate n-acetyl-d-glucosamine (udpag) biosynthesis i.e. l-glutamine: d-fructose 6-p amidotransferase (e.c. 2.6.1.16) was purified 52-fold from human placenta using methanol fractionation and column chromatography on deae-sephadex a-50. the enzyme showed optimal activity in a broad range of ph from 5.8 to 7.8 in both phosphate and cacodylate buffe...

A d-glucosamine 6-phosphate N-acetyltransferase from Blastocladiella emersonii zoospores was partially purified to a specific activity of 2.41 IU per mg of protein. Its pH optimum was 8.05 and its K(m) values were 2.4 x 10(-4) M d-glucosamine 6-phosphate and 0.38 x 10(-4) M Na(3)S-acetyl coenzyme A.

Here we report a novel method for the synthesis of glucosamine-functionalized gold nanoparticles (GlcN-AuNPs) using biocompatible and biodegradable glucosamine for antibacterial activity. GlcN-AuNPs were prepared using different concentrations of glucosamine. The synthesized AuNPs were characterized for surface plasmon resonance, surface morphology, fluorescence spectroscopy, and antibacterial ...

The effects of hexosamines and their acetyl derivatives on the aggregation of 4-dimethylaminoazobenzene-induced rat hepatoma cells, dRLa-74 and dRLh-84, which have a low and high tumor-producing activity, respectively, were examined in rotation-mediated cell culture. D-Glucosamine, D-galactosamine, and D-mannosamine had relatively little effect on aggregation of either strain of hepatoma cells ...
