Basic peptide antibiotic from Bacillus brevis. It exhibits broad-spectrum antibacterial activity and inhibits bacterial DNA synthesis.

Ureohydrolases are a class of enzymes that catalyze the hydrolysis of urea into ammonia and carbon dioxide, which can include urease, urease accessory proteins, and other enzymes with similar functions.

Antibiotic produced by Streptomyces pactum used as an antineoplastic agent. It is also used as a tool in biochemistry because it inhibits certain steps in protein synthesis.

A process of GENETIC TRANSLATION whereby the formation of a peptide chain is started. It includes assembly of the RIBOSOME components, the MESSENGER RNA coding for the polypeptide to be made, INITIATOR TRNA, and PEPTIDE INITIATION FACTORS; and placement of the first amino acid in the peptide chain. The details and components of this process are unique for prokaryotic protein biosynthesis and eukaryotic protein biosynthesis.

Multicomponent ribonucleoprotein structures found in the CYTOPLASM of all cells, and in MITOCHONDRIA, and PLASTIDS. They function in PROTEIN BIOSYNTHESIS via GENETIC TRANSLATION.
