Assembly of the BclB glycoprotein into the exosporium and evidence for its role in the formation of the exosporium 'cap' structure in Bacillus anthracis.

Abstract excerpt

The outermost layer of the Bacillus anthracis spore consists of an exosporium comprised of an outer hair-like nap layer and an internal basal layer. A major component of the hair-like nap is the glycosylated collagen-like protein BclA. A second collagen-like protein, BclB, is also present in the exosporium. BclB possesses an N-terminal sequence that targets it to the exosporium and is similar in sequence to a...
