CLONING, MAPPING AND IDENTIFICATION OF THE AEROMONAS-SALMONICIDA FSTA, FEPA AND IRPA GENES, ENCODING THE 86, 82 AND 74 KDA IRON-REGULATED OUTER-MEMBRANE PROTEINS, RESPECTIVELY

Three iromps (iron-regulated outer membrane proteins) of Aeromonas sal monicida were identified by the use of specific antibodies together wi th Southern hybridization analysis and limited nucleotide sequencing o f their genes. The results of these experiments together with a search of the international database for homologous sequences led to their i dentification as follows: 86 kDa iromp (FstA) as a Vibrio anguillarum Fat A homologue 82 kDa iromp (FepA) as an Escherichia coli FepA homolo gue 74 kDa iromp (IrpA) as an Escherichia coli Cir homologue.
