Seminalplasmin inhibits transcription and translation of φ80 DNA in vitro

Abstract
Seminalplasmin, an antimicrobial protein from bovine seminal plasma that has been earlier shown to inhibit transcription in whole cells and by purified RNA polymerase in vitro, but not translation in whole cells, is now shown to inhibit both transcription and translation independently of each other, in a coupled transcription‐translation system from E. coli using φ80dphoAlacZ DNA as the template.
