title: Molecular cloning and sequence analysis of the gene coding for the 57-kDa major soluble antigen of the salmonid fish pathogen Renibacterium salmoninarum.
abstract: The complete sequence coding for the 57-kDa major soluble antigen of the salmonid fish pathogen, Renibacterium salmoninarum, was determined. The gene contained an opening reading frame of 1671 nucleotides coding for a protein of 557 amino acids with a calculated M(r) value of 57,190. The first 26 amino acids constituted a signal peptide. The deduced sequence for amino acid residues 27-61 was in agreement with the 35 N-terminal amino acid residues determined by microsequencing, suggesting the protein is synthesized as a 557-amino acid precursor and processed to produce a mature protein of M(r) 54,505. Two regions of the protein contained imperfect direct repeats. The first region contained two copies of an 81-residue repeat, the second contained five copies of an unrelated 25-residue repeat. Also, a perfect inverted repeat (including three in-frame UAA stop codons) was observed at the carboxyl-terminus of the gene.
