DESCRIPTION

Also known as RS7_ECOLI, rpsG. One of the primary rRNA binding proteins, it binds directly to 16S rRNA where it nucleates assembly of the head domain of the 30S subunit (PubMed:2461734). Is located at the subunit interface close to the decoding center, where it has been shown to contact mRNA (PubMed:10606263). Has been shown to contact tRNA in both the P and E sites; it probably blocks exit of the E site tRNA (PubMed:8524654)., Protein S7 is also a translational repressor protein; it regulates the expression of the str operon members to different degrees by binding to its mRNA. Part of the 30S ribosomal subunit (PubMed:385062, PubMed:7556101, PubMed:10094780, PubMed:12809609, PubMed:16272117, PubMed:27934701, PubMed:12244297, PubMed:27906160, PubMed:27906161, PubMed:28077875). Contacts proteins S9 and S11 (By similarity). Cross-links to IF3 and the P and E site tRNAs (PubMed:7000779, PubMed:6349681, PubMed:8524654).
