Abstract

The nucleotide sequence of the gene (slpT) encoding the crystalline surface layer protein (SLP) of Rickettsia typhi was determined. The slpT gene consists of 4935 bp coding for a 1645-amino-acid (aa) protein containing a predicted signal peptide at the N terminus. The size of the predicted SLP exceeds the observed size (135 kDa) on SDS-PAGE. The N-terminal aa sequence of the 32-kDa protein of R. typhi reported by Hackstadt et al. [Infect. Immun. 60 (1992) 159-165] was found in the C-terminal portion of the deduced aa sequence, suggesting that the product of slpT is processed into the mature SLP and the 32-kDa protein.
