ABSTRACT
Analysis of seven plasmids (77 to 135 kbp in size) of the P-7 incompatibility group that are responsible for the biodegradation of naphthalene and salicylate has shown that the main natural host of IncP-7 plasmids is the species Pseudomonas fluorescens. The IncP-7 plasmids are structurally diverse and do not form groups, as is evident from their cluster analysis. The naphthalene catabolism genes of six of the IncP-7 plasmids are conservative and homologous to the catabolic genes of NAH7 and pDTG1 plasmids. The pAK5 plasmid contains the classical nahA gene, which codes for naphthalene dioxygenase, and the salicylate 5-hydroxylase gene (nagG) sequence, which makes the conversion of salicylate to gentisate possible.
