FIG. 1.

Nucleotide sequence of the 3′ region of lytA and nanA. The deduced amino acid sequence and position are shown below the sequence. For lytA, a 189-bp region found in the nucleotide sequence of R6, but not the nonautolytic mutant P24, and the corresponding amino acid sequence are indicated in boldface. The positions of nontandem direct nanomer repeats flanking the deletion in the R6 lytA are shown by underlining. For nanA, a 180-bp region found in the nucleotide sequence of R6, but not TIGR4, and the corresponding amino acid sequence are indicated in boldface. The positions of nontandem direct octomer repeats, two of which flank the deletion in the R6 nanA, are shown by underlining. The predicted length of the intact protein is indicated in parentheses.
