CC -!- FUNCTION: During stationary phase prevents 70S dimer formation, CC probably in order to regulate translation efficiency during transition CC between the exponential and the stationary phases (PubMed:16324148). CC During environmental stress such as cold shock or excessive cell CC density at stationary phase, stabilizes the 70S ribosome against CC dissociation, inhibits translation elongation and increases translation CC accuracy (PubMed:11375931, PubMed:15219834). When normal growth CC conditions are restored, is quickly released from the ribosome CC (PubMed:11375931). Has been suggested to inhibit translation elongation CC by blocking the A-site (aminoacyl-tRNA site) (PubMed:11375931). Has CC also been suggested to inhibit translation initiation by blocking the CC A-site and P-site (peptidyl-tRNA site) of the ribosome CC (PubMed:15502846, PubMed:23420694). At 15 degrees Celsius binds 30S CC subunits and stimulates their association with 50S subunits into idle CC 70S ribosomes (PubMed:23420694). Crystallization with T.thermophilus CC 70S ribosomes shows it binds in the channel between the head and body CC of the 30S subunit, where mRNA, tRNAs, initiation factors IF1 and IF3 CC and elongation factor G would bind; this protein's extended tail CC follows the mRNA channel and probably prevents RMF binding, which would CC prevent ribosome dimerization (PubMed:22605777). This protein also CC stabilizes the 30S head relative to the rest of the ribosome, which may CC also prevent dimerization (PubMed:22605777). Counteracts miscoding CC (translation errors) particularly efficiently at magnesium CC concentrations close to those observed in vivo but less efficiently at CC higher concentrations (PubMed:15219834). Counteraction of miscoding was CC shown to be stronger than inhibition of translation, suggesting that CC the former activity could be the main function of this protein in vivo CC (PubMed:15219834). {ECO:0000269|PubMed:10535924, CC ECO:0000269|PubMed:11168583, ECO:0000269|PubMed:11375931, CC ECO:0000269|PubMed:15219834, ECO:0000269|PubMed:15502846, CC ECO:0000269|PubMed:16324148, ECO:0000269|PubMed:22605777, CC ECO:0000269|PubMed:23420694}. CC -!- SUBUNIT: Associates mainly with 70S ribosomes (PubMed:11168583, CC PubMed:11375931). Localized at the surface of the 30S ribosomal CC subunit, at the interface with the 50S subunit (PubMed:10535924, CC PubMed:15502846, PubMed:22605777). Binds across the channel in the 30S CC subunit where tRNAs and mRNA interact during protein biosynthesis CC (PubMed:15502846, PubMed:22605777). Can also associate with 100S CC ribosomes, which are inactive dimers of 70S ribosomes CC (PubMed:11168583). Contacts modified methylated residues of 16S rRNA CC (in complex with T.thermophilus ribosome, 2/3 residues are also CC modified in E.coli) (PubMed:25775268). {ECO:0000269|PubMed:10535924, CC ECO:0000269|PubMed:11168583, ECO:0000269|PubMed:11375931, CC ECO:0000269|PubMed:15502846, ECO:0000269|PubMed:22605777, CC ECO:0000269|PubMed:25775268, ECO:0000269|PubMed:26792896}. CC -!- INTERACTION: CC P0AD49; P0A805: frr; NbExp=4; IntAct=EBI-1129692, EBI-1114349; CC -!- INDUCTION: During stationary phase (at protein level) (PubMed:11168583, CC PubMed:11375931). Also by cold stress, remains ribosome-associated for CC the 4 hours tested, then disappears when cells are warmed (at protein CC level) (PubMed:11375931, PubMed:23420694). CC {ECO:0000269|PubMed:11168583, ECO:0000269|PubMed:11375931, CC ECO:0000269|PubMed:23420694}. CC -!- MASS SPECTROMETRY: Mass=12640; Method=MALDI; CC Evidence={ECO:0000269|PubMed:10535924}; CC -!- DISRUPTION PHENOTYPE: Non-essential gene, increased formation of CC inactive 100S ribosomes in stationary phase, which persist longer than CC in wild-type. Double hpr-yfiA deletion mutants form 90S ribosomes CC (PubMed:16324148). A quadruple yfiA-hpf-rmf-sra knockout strain is CC significantly outcompeted by wild-type after 4 days growth CC (PubMed:17277072). No visible effect on viability or growth rate at 37 CC or 10 degrees Celsius, slight effect on bulk translation and timing of CC expression of some cold-shock proteins (PubMed:23420694).
