With S5 and S12 plays an important role in translational accuracy; many suppressors of streptomycin-dependent mutants of protein S12 are found in this protein, some but not all of which decrease translational accuracy (ram, ribosomal ambiguity mutations). S4 represses its own expression; it is not know if this is at the level of translation or of mRNA stability.

While neither of the L31 paralogs is essential, this protein seems to function as the main L31 protein. Has a lower affinity for 70S ribosomes than the non-zinc-containing paralog L31B (ytiA); is displaced by it to varying extents, even under zinc-replete conditions. [[http://www.uniprot.org/uniprot/RL5_BACSU RL5_BACSU]] This is 1 of the proteins that binds and probably mediates the attachment of the 5S RNA into the large ribosomal subunit, where it forms part of the central protuberance. In the 70S ribosome it contacts protein S13 of the 30S subunit (bridge B1b), connecting the 2 subunits; this bridge is implicated in subunit movement. Contacts the P site tRNA; the 5S rRNA and some of its associated proteins might help stabilize positioning of ribosome-bound tRNAs (By similarity). [[http://www.uniprot.org/uniprot/RS10_BACSU RS10_BACSU]] Involved in the binding of tRNA to the ribosomes.

This enzyme catalyzes the formation of pppGpp which is then hydrolyzed to form ppGpp, it is probably the hydrolysis activity that is required for optimal growth (Probable).<ref>PMID:18067544</ref> [[http://www.uniprot.org/uniprot/RL14_BACSU RL14_BACSU]] Binds to 23S rRNA. Forms part of two intersubunit bridges in the 70S ribosome (By similarity). [[http://www.uniprot.org/uniprot/RS12_BACSU RS12_BACSU]] With S4 and S5 plays an important role in translational accuracy. Interacts with and stabilizes bases of the 16S rRNA that are involved in tRNA selection in the A site and with the mRNA backbone. Located at the interface of the 30S and 50S subunits, it traverses the body of the 30S subunit contacting proteins on the other side and probably holding the rRNA structure together.
