چکیده

Commercial staphylococcal nuclease (Foggi strain) containing small amounts of contaminating protein can be purified by chromatography on phosphorylated cellulose columns. The purified enzyme is free of acid and alkaline phosphatase activities. It is homogeneous by polyacrylamide gel electroptfresis, and antigenically pure by immunodiffusion. The E” 1 Cm of the pure enzyme at neutral pH is 9.3 at 280 rnp and 9.7 at 277 mp.

Purification and properties of semisynthetic staphylococcal nuclease-T'.

Semisynthetic staphylococcal nuclease-T’, the noncovalent complex of peptide fragments synthetic-(6-4’7) (the peptide, obtained by solid phase synthesis, corresponding to Residues 6 through 47 of nuclease) and native nuclease-T(49-149) (containing Residues 49 through 149 of nuclease), was isolated in a highly purified form. This material was compared to native nuclease-T’, the complex of native...

Solid phase synthesis of a 42-residue fragment of staphylococcal nuclease: properties of a semisynthetic enzyme.

The polypeptide corresponding to the amino acid sequence from residue 6 through 47 in staphylococcal nuclease has been synthesized by the solid-phase method. The synthetic product closely resembles the corresponding native polypeptide in both physical and chemical properties. The synthetic peptide may be recombined with the complimentary native peptide comprising residues 49 through 149 to form...

An efficient fusion expression system for protein and peptide overexpression in Escherichia coli and NMR sample preparation.

An efficient fusion expression system with a small fusion partner, His6-tagged N-terminal fragment of staphylococcal nuclease R, has been constructed and tested with two genes. The results show that the system is not only suitable for overexpression of small proteins and peptides but simplifies purification of target proteins and peptides. The study also provides a practical method for preparat...

Reduction of cell lysate viscosity during processing of poly(3-hydroxyalkanoates) by chromosomal integration of the staphylococcal nuclease gene in Pseudomonas putida.

Poly(3-hydroxyalkanoates) (PHAs) are biodegradable thermoplastics which are accumulated by many bacterial species in the form of intracellular granules and which are thought to serve as reserves of carbon and energy. Pseudomonas putida accumulates a polyester, composed of medium-side-chain 3-hydroxyalkanoic acids, which has excellent film-forming properties. Industrial processing of PHA involve...

Purification of human anti-erythropoietin polyclonal antibodies by precipitation and chromatography as an optimized method with potential application in vaccine studies

Introduction: Polyclonal antibodies are required to be affinity purified. Improved purification methods of polyclonal antibody provide an opportunity to pick the most purified immunoglobulins as a primary or secondary antibody in immunoassays that are included in many vaccine studies. Two common techniques for purifying proteins is salt precipitation and chromatography purification. Our work fo...
