Expression and purification of recombinant K1, K5, and K30 depolymerases. (A) SDS-PAGE showing induced expression and purification of K1E, K1F, and K1H depolymerases. 50 μg of uninduced or induced whole cell lysate obtained after sonication, or 2 μg of enzyme purified was fractionated by SDS-PAGE followed by Coomassie Blue staining. U, uninduced whole cell lysate; I, induced whole cell lysate; P, purified enzyme. (B) SDS-PAGE of K5 and putative K30 depolymerases after a similar induction and protein purification.
