Penicillium verruculosum으로부터 D-xylanase II의 정제 및 특성

Purification and Characterization of D-Xylanase II from Penicillium verruculosum

Xylanase(1, 4-beta-D-xylan xylanohydrolase` EC 3.2.1.8) II was purified from Penicillium verruculosum by using the techniques of two anion exchange chromatographies, and gel filtration. The molecular weight of this enzyme was about 22, 000 as determined by SDS-electrophoresis. The enzyme showed hydropytic activity toward xylan but did not catalyze hydrolysis of Rho-nitrophenyl-beta-D-xylopyranoside, Rho-nitrophenyl-beta-D-glucopyranoside, Rho-nitrophenyl-beta-D-cellobiopyranoside, and celluloses such as Avicel, cotton, filter paper, carboxymethylcellulose.
