Abstract: | The locations of ribosome binding sites on the right end of bacteriophage lambda DNA were determined by measurement of the positions of ribosomes bound to single-stranded DNA visualized by electron microscopy. A total of ten ribosome binding sites were found between map co-ordinates 0.90 and 1.0. Four of these ribosome binding sites probably correspond to the polypeptide initiation sites for genes Q (0.910), S (0.928), R (0.936) and Rz (0.945). Six other ribosome binding sites were found which presumably indicate the presence of new lambda genes. Four of these ribosome binding sites (0.958, 0.967, 0.975, 0.995) are located to the right of Rz, which is the most rightward known lambda gene. A ribosome binding site is located at 0.923, between genes Q and S, in or near the 6 S RNA sequence. Another is located left of gene Q at 0.900. |
