title: Positions of S2, S13, S16, S17, S19 and S21 in the 30 S ribosomal subunit of Escherichia coli.
abstract: Neutron scattering distance data are presented for 33 protein pairs in the 30 S ribosomal subunit from Escherichia coli, along with the methods used for measuring distances between its exchangeable components. When combined with prior data, these new results permit the positioning of S2, S13, S16, S17, S19 and S21 in the 30 S ribosomal subunit, completing the mapping of its proteins by neutron scattering. Comparisons with other data suggest that the neutron map is a reliable guide to the quaternary structure of the 30 S subunit.
