T7 RNA polymerase

T7 RNA polymerase is a highly specific and efficient enzyme derived from bacteriophage T7 produced in Escherichia coli. T7 RNA polymerase is responsible for synthesizing RNA from DNA templates that contain a T7 promoter sequence. Its remarkable specificity for this promoter ensures that only the desired target sequence is transcribed, minimizing off-target effects. Unlike many host RNA polymerases, T7 RNA polymerase operates independently of cellular machinery, making it an ideal tool for controlled transcription in a laboratory setting.
