Recombinant Escherichia coli 30S ribosomal protein S7 (rpsG)
Description
Purity > 90% as determined by SDS-PAGE. MW: 23.9kDa. Full Length of Mature Protein: 2-179aa. N-terminal 6xHis-tagged. Escherichia coli (strain K12). One of the primary rRNA binding proteins, it binds directly to 16S rRNA where it nucleates assbly of the head domain of the 30S subunit. Is located at the subunit interface close to the decoding center, where it has been shown to contact mRNA. Has been shown to contact tRNA in both the P and E sites; it probably blocks exit of the E site tRNA.
