Application

Application Comment Organism
degradation conservation of the Cys-45 residue in human E3 is essential to the efficient catalytic function of the enzyme Homo sapiens

Cloned(Commentary)

Cloned (Comment) Organism
expressed in Escherichia coli XL1-Blue Homo sapiens

Protein Variants

Protein Variants Comment Organism
C45S Ser-45 mutant is highly purified, shows 5270fold lower activity than wild-type enzyme. Destroyed disulfide bond between Cys-45 and Cys-50 of the active disulfide center in human E3. UV-visible spectrum of the Ser-45 mutant is similar to that of the reduced form of the enzyme and the second fluorescence emission of the mutant disappears Homo sapiens
C45Y purification of the Tyr-45 mutant is not successful. Recombinant human E3 becomes too unstable to be easily obtained from Escherichia coli Homo sapiens
