Figure 1.

ClustalW alignment of PstI sequences and the PstI recognition sequence. The PstI sequence was compared to PstI RS repeats (direct, D and reverse, R readings) by two different ways: as nucleic acids [NA, N] or as overlappingly translated [OTS, P] and regularly translated [PROT] sequences. The result of the alignments is visualized by Jalview where the shaded areas emphasize sequence identity. Only a short fragment of the alignments is shown.
