The 30 S subunit of the Escherichia coli ribosome. Topographical model of its component proteins.
This topographical model of the proteins of the 30 S subunit of the Escherichia coli ribosome was built to be consistent with the 37 published spectroscopic and chemical experiments that indicate proximity and with the two neutron diffraction experiments that indicate S3 and S7 as well as S2 and S5 to be separated by 110 A. The model is quite consistent with the protein arrangement suggested by assembly pathways, the various RNA binding sites, and the streptomycin-associated proteins, This consistency is encouraging since none of these data were considered during the construction of the model. The model differs significantly from those proposed by Traut et at. ((1974) Ribosomes 271-308) and by Tischendorf et al. ((1975) Proc. Natl. Acad. Sei. U.S. 72, 4820-4824).
