General annotation (Comments)

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 tRNA in the A and P-sites By similarity.
Subunit structure	Part of the 30S ribosomal subunit. Has been shown to cross-link to S19 forming a loose heterodimer. Forms two bridges to the 50S subunit in the 70S ribosome By similarity.
Sequence similarities	Belongs to the ribosomal protein S13P family.
