摘要: 1.0 M NH4Cl washes of E. coli ribosomes contain two protein factors affecting activities the polypeptide chain initiation factor 3 (IF3). One (iα) inhibits functions IF3α, IF3 species which recognizes MS2, coli, and early T4 RNA; other (iβ) IF3β, recognizing late RNA. Initiation complex formation translation mRNA are inhibited to same extent but ribosome dissociation activity is not affected.
