摘要

The amp gene of pBR328 and pBR322 was expressed less efficiently at 45 than at 30 degrees C in an in vitro coupled transcription-translation system of Escherichia coli. Preincubation of S30 extract at 45 degrees C reduced specifically its ability to express the amp gene at 30 degrees C, indicating inactivation of a factor(s) required for efficient expression of the amp gene.
