The cbsA gene encoding the collagen-binding S-layer
protein of Lactobacillus crispatus JCM5810 was expressed in
L. casei ATCC 393T. The S-protein was not
retained on the surface of the recombinant bacteria but was secreted
into the medium. By translational fusion of CbsA to the cell wall
sorting signal of the proteinase, PrtP, of L. casei, CbsA
was presented at the surface, rendering the transformants able to bind
to immobilized collagens.
