Aktivitas antimutagen isoflavon glokosida hasil transglikosilasi enzimatik CGT - ase bacillus macerans : Antimutagen activity of synthesized isoflavone glycoside by enzymatically transglycosylation
" It has been known that isoflavone have biological activities such as antioxidant, antibacteria, antimutagenesis, and anticancer. Isoflavone aglycone uses such as genestein, daidzein and glycitein are li ited since they are unstable and uneasily to dissolve in water... ... "

Pemurnian protein rekombinan sukrosafosforilase dari leuconostoc mesenteroides MBFWRS-3(1) yang diekspresikan di escherichia coli BL21DE = Purification protein recombinant sucrosephosporylase from leuconostoc mesenteroides MBFWRS-3(1) which is expressed in escherichia coli BL21DE
" Enzim sukrosafosforilase termasuk dalam kelompok enzim glukosiltransferase. yang dapat mengkatalisis sukrosa dan fosfat menjadi Ɗ-fructose dan α-Ɗ-glucose 1-phospate. SPase berperan dalam pemindahan gugus glukosil ke sejumlah senyawa (transglikosilasi). Reaksi transglkosilasi dapat dimanfaatkan untuk meningkatkan stabilitas kimia dan memperbaiki karakteistik senyawa bioaktif. Tujuan penelitian ini adalah melakukan pemurnian SPase rekombinan yang dihasilkan oleh Escherichia coli BL21DE yang membawa gen penyandi sukrosafosforilase asal Leuconostoc mesenteroides dengan kromatografi affinitas pada kondisi optimum dan menguji aktivitas SPase rekombinan dengan metode ...

Acceptor specificity of recombinant cyclodextrin glycosyltransferase from bacillus circulans A11
" ABSTRACT
Cyclodextrin glycosyltransferase (CGTase) catalyzes an intermolecular transglycosylation reaction to produce functional oligosaccharides or glycosides, which can be used in several industries. In this study, the p19bBC recombinant cells containing CGTase gene from Bacillus circulans A11 were used for synthesizing CGTase. The maximum expression was obtained when the p19bBC cells were cultured at 37oC for 24 h with 0.2 mM IPTG. The recombinant CGTase was purified up to 6-fold by 5% (w/v) starch adsorption and the ... "
