Table 6.
Spacer sequence matches to viruses, plasmids and chromosomes. Lengths of the sequence matches are given in columns 3–5 where sequence identity ranged from 88 to 100%. For transposase genes only the best match is given. For M. thermoautotrophicus, there were three matches to phage ΨM2 ORF6 and two to prophage ΨM100 ORF31.
