Purification and from Properties of Pseudomonas Cephalosporinase Aer Uginosa
Cephalosporin j3-lactamase (cephalosporinase; CSase) was purified from a strain of Pseudonzonas aeruginosa resistant to ~-lactam antibiotics. The purified enzyme preparation gave a single protein band on sodium dodecyl sulfate-polyacrylamide gel electrophoresis, and its molecular weight was about 34,000. The specific activity was 49.7 ilmoles/minute/mg of protein of the purified enzyme for the ...
متن کاملPurification and Properties of Nitrate Reductase from Escherichia coli KlZ*
The membrane-bound enzyme nitrate reductase from Escherichia coli has been solubilized and purified 112-fold. The purified enzyme appeared homogeneous by polyacrylamide gel electrophoresis and in the analytical ultracentrifuge. The molecular weight of the enzyme, as measured on an agarose column, was 720,000 and, as measured in the ultracentrifuge, was 773,600. The SO value was determined by se...
متن کاملPurification and properties of beta-N-acetylglucosaminidase from Escherichia coli.
beta-N-acetylglucosaminidase (EC 3.2.1.30) has been purified from Escherichia coli K-12 to near homogeneity based on polyacrylamide gel electrophoresis in both 0.5% sodium dodecyl sulfate and in 6 M urea at pH 8.5. The purified enzyme shows a pH optimum of 7.7 and the Km for p-nitrophenyl-beta-D-2-acetamido-2-deoxyglucopyranoside is 0.43 mM. The molecular weight of this enzyme, determined by bo...
متن کاملPurification and properties of polynucleotide phosphorylase from Escherichia coli.
A method for the purification of polynucleotide phosphorylase from Escherichia coli has been developed. The purified enzyme has a specific activity 700-fold higher than the crude extract. When enzyme fractions obtained at different stages of the purification were assayed by phosphorolysis of polyadenylic acid (poly A) or 32P-orthophosphate exchange with the S’diphosphates of adenosine, uridine,...
