FIG 1.
Transposon sequence identification by sequence alignment. A diagram of the native dysfunctional CYP153AM.aq operon is shown in the upper panel. The open reading frames of the transposase and the helper protein are shown in blue. The sequences of these are shown in the lower panel. The transposon belongs to the IS21 family, with 10 other homologs being present in the genome of M. aquaeolei VT8 (90 to 100% identities). All paralogs have the same imperfect terminal inverted repeats (13 bp and 12 bp long, indicated by the arrows above the sequences) and a 6-bp target site duplication. FdX, ferredoxin; FdR, ferredoxin reductase.
