FIG. 4.

Nucleotide sequence alignment of ermG genes from CTn7853, B. sphaericus, and CTnGERM1. Each hyphen (-) represents a gap inserted because of dissimilarities in the alignment. ∗, 100% nucleotide identity of the three sequences. Lowercase letters were used when one of the sequences differed. The ermG start codon ATG and stop codon TAA are shown in boldface. The extended sequence identity between CTnGERM and the B. sphaericus ermG is continued at the bottom. The nucleotide position numbers are relative to the A of the ATG start codon: + for downstream positions and − for upstream positions. Alignment was performed with the ClustalW program. GenBank accession numbers are as follows: CTn7853, L42817; ermG region from B sphaericus, M15332; and CTnGERM1, AJ557257.
