载体描述:
pPIC9 was used as a template and α-factor gene of Saccharomyces cerevisiae was amplified by PCR. The gene was cloned in the intracellular expression vector pYES2/CT for Saccharomyces cerevisiae and the secreting expression vector named pYES2/CT/α-factor(pYCα) was constructed. The gene of mannase(man) from recombinant vector of pKLAC1-man (pKLman) was cut by restriction enzymes and linked with pYCα. This recombinant vector pYCα-man was used to determine the secretory ability and stability of pYCα. The excellent secretory ability of pYCα was proved by two experiments. One showed that INVSc1/pYCα-man clones formed the clear rings around the clones on the medium contained trypan blue, while INVSc1/pYCα clones had no rings.Further analysis of mannase activity of extracellular supernatant and intracellular extracts showed that both extracellular and intracellular mannase activities of INVSc1/pYCα were not detected,while INVScl/pYCα-man had evident extracellular mannase activities and no intracellular mannase activities. The stability of pYCα was also very good proved by continuous cultivation for about 150h.

以pPIC9为模板,通过PCR扩增获得酿酒酵母的α-交配因子(α-factor),并克隆至酿酒酵母胞内表达载体pYES2/CT中,构建了一种新型酿酒酵母附加型分泌表达载体pYES2/CT/α-factor(pYCα)。
