Mutant AOX2 promoter, microorganism carrying same, method of preparation
thereof and production of heterologous protein using such microorganism
摘要:
A mutant AOX2 (alcohol oxidase 2) promoter derived from the natural AOX2 promoter by base sequence deletion, insertion, or substitution is disclosed. A microbial strain carrying a gene under the control of such a mutant AOX2 promoter can be obtained by growing in a methanol-containing medium a strain incapable of producing AOX encoded by the AOX1 gene but carrying the AOX2 gene under the control of the natural AOX2 promoter. A heterologous protein may be produced by cultivating the mutant strain with the desired heterologous protein gene incorporated downstream from the mutant AOX2 promoter. A plasmid carrying the mutant AOX2 promoter is also provided.
