Small ribosomal subunit protein uS13

UniProt P9WH61 Organism Mycobacterium tuberculosis (strain ATCC 25618 / H37Rv) Gene Rv3460c, rpsM

Also known as: Rv3460c, rpsM

Function

Located at the top of the head of the 30S subunit, it contacts several helices of the 16S rRNA. In the 70S ribosome it contacts the 23S rRNA (bridge B1a) and protein L5 of the 50S subunit (bridge B1b), connecting the 2 subunits; these bridges are implicated in subunit movement. Contacts the tRNAs in the A and P-sites.
