Protein Domain : Exosporium BclB, C-terminal IPR021210

Type	Domain
Description	This domain occurs as the C-terminal region in a number of proteins that have extensive collagen-like triple helix repeat regions. Member domains are predicted by TmHMM to have four or five transmembrane helices. Proteins in this entry are found mostly in the Firmicutes, but also in Acanthamoeba polyphaga mimivirus. This entry includes spore surface glycoprotein BclB from Bacillus anthracis, a protein of the exosporium. The exosporium is an additional outermost spore layer, lacking in Bacillus subtilis and most other spore formers, consisting of a basal layer and, above it, a nap of fine filaments.Proteins containing this domain also include some uncharacterised virus proteins.
Short Name	Exosporium_BclB
