The initiation factor IF3 is platinated with trans-diamminedichloroplatinum(II) and cross-linked to Escherichia coli 30S ribosomal subunit. Two cross-linking sites are unambiguously identified on the 16S rRNA: a major one, in the region 819-859 in the central domain, and a minor one, in the region 1506-1529 in the 3'-terminal domain. Specific features of these sequences together with their particular location within the 30S subunit lead us to postulate a role for IF3, that conciliates topographical and functional observations made so far.
