Table 5. Putative open reading frames identified on the 13.1 kbp and 9.5 kbp plasmids of P. pastoris.
All protein sequences were analyzed using blastp (protein-protein blast) against the non-redundant protein database. The protein entries showing the highest sequence identity to the query are summarized. No homologues of the gamma toxin subunit or the antitoxin gene were identified on the two P. pastoris killer plasmids.
