a
Parentheses indicate that the ORF or control site is on the complementary strand in the sequence compiled in GenBank accession no. AF071413.
b
There are two possible −10 and −35 promoter regions for tnpM; however, neither conform well to the consensus sequence for ς−70 RNA polymerase. Both lie within the left end of In2.
