| Abstract: | A study was made of the ability of reference plasmids of the 6 known Fin-groups to inhibit the functions of transfer genes (tra-genes) of the 4 derepressed F-like plasmids (pAP22-2, pAP38, pAP43, pAP53). It was shown that unlike the derepressed Flac plasmid, the conjugation transfer of pAP38 and pAP53 plasmids was inhibited only by, the FinV plasmid, whereas pAP22-2 plasmids by Fin V and Fin V plasmids. The formation of donor-specific pili in case of pAP38 plasmid was inhibited by Fin Q, Fin U and Fin V plasmids, in case of pAP43 plasmid by Fin U Fin V and Fin W plasmids. |
