Peptide Initiation Factors

Medical Definition:	Protein factors uniquely required during the initiation phase of protein synthesis in GENETIC TRANSLATION.
Guide Notes:	GEN or unspecified; prefer specifics
Previously Indexed:	Bacterial Proteins (1966-1972),Peptides (1966-1972),Proteins (1966-1972)

Peptide Initiation Factors Categories.

	Eukaryotic Initiation Factors - Peptide initiation factors from eukaryotic organisms. Over twelve factors are involved in PEPTIDE CHAIN INITIATION in eukaryotic cells. Many of these factors play a role in controlling the rate of MRNA TRANSLATION.
	Prokaryotic Initiation Factors - Peptide initiation factors from prokaryotic organisms. Only three factors are needed for translation initiation in prokaryotic organisms, which occurs by a far simpler process than in PEPTIDE CHAIN INITIATION of eukaryotic organisms.
