摘要:Expression in mycobacteria of the structural gene sacB, which encodes the Bacillus subtilis levansucrase(果聚糖蔗糖酶), was investigated. sacB expression is lethal to Mycobacterium smegmatis and Mycobacterium bovis BCG in the presence of 10% sucrose. sacB could thus be used as a counterselectable marker in mycobacteria.
