Cloned(Commentary)

Cloned (Comment) Organism
wild type and R210K mutant enzymes are expressed in Escherichia coli BL21(DE3) pLysS cells Drosophila melanogaster

Protein Variants

Protein Variants Comment Organism
R210K essentially inactive, the point mutation in kinesin heavy chain disrups the ability of the enzyme active site to catalyze ATP P-O bond cleavage, pairing the inactive R210K subunit with a wild type subunit produces a dimer with essentially the full mechanochemical function of homodimeric wild type kinesin-1 Drosophila melanogaster
