Transcription terminator and related recombinant DNA vectors and transformants

摘要

A transcription terminator is disclosed comprising a DNA sequence capable of functioning as a transcription terminator in a microorganism of the order Actinomycetales. These transcription terminators are functional in both gram-positive and gram-negative microorganisms, especially Streptomyces ambofaciens. Additionally, a series of recombinant DNA cloning vectors suitable for isolating the disclosed transcription terminators are set forth.
