ABSTRACT
Bacillus anthracis collagen-like protein(BclA) is a structural component of the exosporium filaments,as well as the immunodominant antigen on the spore surface.The genes encoding BclA proteins were cloned and sequenced from three Bacillus anthracis strains separated from China.It was founded that the BclA proteins of strain A16R and 40048,containing 388 and 322 amino acids,72 and 50 copies of GXX repeat,5 and 3 copies of 21-amino-acid sequence(GPT)_(5)GDTGTT(BclA repeat) respectively,are different from those reported by foreign scholars;while the BclA protein of strain 40022,containing 370 amino acids,66 copies of GXX repeat,and 5 copies of BclA repeat,is identical with that of strain 53169 reported by others.The results are helpful for the molecular typing of B.anthracis strains,and provide a basis for the elucidation of the pathogenesis and immunogenicity of B.anthracis spore.
