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

Abstract

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