Cloned(Commentary)

Cloned (Comment) Organism
DNA and amino acid sequence determination and analysis, expression of His-tagged enzyme in Escherichia coli strain BL21(DE3) at 37°C and at 15°C. The recombinant alginate lyase expressed with pColdI at 15°C exhibits the highest alginate-degrading activity, method evaluation and optimization Streptomyces sp.

Protein Variants

Protein Variants Comment Organism
additional information recombinant alginate lyase is efficiently immobilized onto two types of magnetic nanoparticles, superparamagnetic iron oxide nanoparticle, and hybrid magnetic silica nanoparticle, based on the affinity between His-tag and Ni2+ displayed on the surfaces of nanoparticles. An alginate oligosaccharide mixture consisting of dimer and trimer is synthesized by the immobilized alginate lyase. The immobilized enzymes can be re-used repeatedly more than 10 times after magnetic separation, overview Streptomyces sp.
