MeSH Heading
Peptide Chain Initiation, Translational
Tree Number(s)
Unique ID
RDF Unique Identifier
coordinate with specific peptide; for protein biosynthesis on the ribosome only; for non-ribosomal biosynthesis use PEPTIDE BIOSYNTHESIS, NUCLEIC ACID-INDEPENDENT
Scope Note
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.
