Affinity Purification and Characterization of Recombinant Bacillus sphaericus Phenylalanine Dehydrogenase Produced by pET Expression Vector System

Cloning and expression of the L-phenylalanine dehydrogenase gene, from B. sphaericus in E. coli were done. The gene was cloned in the vector pET16b and transformed into E. coli BL21 (DE3). The functional form of the L-phenylalanine dehydrogenase enzyme was purified by affinity purification techniques, taking advantage of the ability of this enzyme to bind to the nucleotide site affinity dye, Re...

Recombinant production and affinity purification of the FraC pore forming toxin using hexa-His tag and pET expression cassette

Objective(s): A newly-introduced protein toxin from a sea anemone, namely fragaceatoxin C is a protein with molecular weight of 20 kDa and pore-forming capability against cell membranes has recently grasped great attentions for its function. In this study, its coding sequence cloned as a fusion protein with His-tag for simple production and rapid purification. Materials and Methods: After PCR a...

Effects of an abasic site on triple helix formation characterized by affinity cleaving.

The stability of triple helical complexes of pyrimidine oligodeoxyribonucleotides containing one abasic 1,2-dideoxy-D-ribose (phi) residue was examined by affinity cleaving. Within a pyrimidine third strand, the triplets phi.AT, phi.GC, phi.TA and phi.CG are significantly less stable than the triplets, T.AT, C+GC and G.TA. The decrease in binding produced by an abasic residue is similar to that...
