Abstract
It was previously shown that the surface (S)-layer proteins covering the cell surface of Lactobacillus crispatus K313 were involved in the adherence of this strain to human intestinal cell line HT-29. To further elucidate the structures and functions of S-layers, three putative S-layer protein genes (slpA, slpB, and slpC) of L. crispatus K313 were amplified by PCR, sequenced, and characterized in detail. Quantitative real-time PCR analysis reveals that slpA was silent under the tested conditions; whereas slpB and slpC, the putative amino acid sequences which exhibited minor similarities to the previously reported S-layer proteins in L. crispatus, were actively expressed. slpB, which was predominantly expressed in L. crispatus K313, was further investigated for its functional domains. Genetic truncation of the untranslated leader sequence (UTLS) of slpB results in a reduction in protein production, indicating that the UTLS contributed to the efficient S-layer protein expression. By producing a set of N- and C-terminally truncated recombinant SlpB proteins in Escherichia coli, the cell wall-binding region was mapped to the C terminus, where rSlpB380–501 was sufficient for binding to isolated cell wall fragments. Moreover, the binding ability of the C terminus was variable among the Lactobacillus species (S-layer- and non-S-layer-producing strains), and teichoic acid may be acting as the receptor of SlpB. To determine the adhesion region of SlpB to extracellular matrix proteins, ELISA was performed. Binding to immobilized types I and IV collagen was observed with the His-SlpB1–379 peptides, suggesting that the extracellular matrix protein-binding domain was located in the N terminus.
