Scientific context
The actinomycins are a class of polypeptide antibiotics. Actinomycin D inhibits transcription by binding DNA at the transcription initiation complex and preventing elongation by RNA polymerase (1). Actinomycin D has been used as a chemotherapy drug (2), and an antibiotic.

Additional description
Tissue, pathway, proteinase, peptidase, protease ,acrosin, lipoprotein, activator, caspase, trypsin, papain, esterase inhibitors are proteins or receptor ligands or receptor antagonists that bind to an enzyme receptor and decreases its activity. Since blocking an enzyme's activity can kill a pathogen or correct a metabolic imbalance, many drugs are enzyme inhibitors. Not all receptor antagonist that bind to enzymes are inhibitors; enzyme activator ligands or agonists bind to enzymes and increase their enzymatic activity, while enzyme substrates bind and are converted to products in the normal catalytic cycle of the enzyme. The activation of transcription factor subunits is the first step of gene expression, in which a particular segment of DNA is copied into RNA (mRNA) by the enzyme RNA polymerases. Transcription factors, unites and elongations can be RNA and DNA nucleic acids, base pairs of nucleotides . Converting from DNA to RNA is made by enzymatic reactions. During transcription, a DNA sequence is read by an RNA polymerase, which produces a complementary, anti-parallel RNA strand called a primary transcript. Transcriptions are key functions in signal transduction pathways. Signaling ligand binding transcription factors play an important role in transduction cascades.
