摘要
A cell-free extract of Sulfolobus shibatae is able to specifically initiate transcription in vitro at the promoter of the plasmid-encoded gene for the major gas vesicle protein of Halobacterium halobium and at the promoter for the transcript T4 of the temperature H. halobium phage PHI-H. The corresponding promoter from the virulent phage mutant PHI-HL1 yields enhanced transcription in the heterologous system, in agreement with strongly increased in vivo expression.
