Effect of seminal plasmin on rRNA synthesis in Saccharomyces cerevisiae

Abstract
Seminal plasmin, the highly basic, antimicrobial protein, isolated from bull semen, was found to inhibit the transcription of ribosomal RNA in yeast. Protein synthesis and processing of rRNA remained unaffected. Seminal plasmin appears to be useful for studies of the biosynthesis of yeast rRNA in pulsechase experiments
