摘要
Endo-β-glucanase II(EG II)gene cDNA was isolated from the fungus Humicola insolens H31-3 by RT-PCR.It was cloned into the expression vector pGAPZαA.The resultant recombinant plasmid was introduced into Pichia pastoris GS115 by electroporation after being linearized by BspHI digestion.The recombinant Pichia pastoris strain was obtained and SDS-PAGE showed that the molecular weight of the expression protein was about 55 kD.The cultivation condition and the characteristics of the recombinant EG II were also explored.
