Lacosamide was prepared by chemical method coupled with enzymatic method. N-Acetyl-D, L-3-methoxy-alanine, derived from D,L-3-methoxy-alanine, was used in the resolution process catalyzed by immobilized Escherichia co...
Aspergillus oryzae 3042 mycelium pellets were immobilized by crosslinking method with reagents of gelatin and formaldehyde. An orthogonal design table was used to determine the optimal immobilization conditions. The L...

Control of aggregation, by lowering temperature and protein concentrations, can enhance the extent of successful refolding. The low temperature has been used in protein folding studies, as undesired aggregations often...
Kidney and other tissues of animals and humans have a high concentration of citrate which is an important intermediate substance in the citrate cycle. Citrate may play an important physiological role in metabolism. ...
Some have suggested that the refolding of denatured aminoacylase is difficult. The present study reports that aminoacylase denatured in urea concentrations more than 4?mol/L was markedly but partially unfolded and cou...
The surface of silica gels was modified by an diethylamino group and an hydroxy group, simultaneously. The activity of the aminoacylase immobilized on such amino-hydroxy-silica gels was 316.8 U/g. By its catalysis, th...
Aminoacylase was immobilized on the mycelium cells of Aspergillus oryzae by using ethylenediamine, gelatin and glutylalhyde. The proper immobilized condition was studied by orthogonal experimental design. The immo...
