Names: Avidin-like domain
Function: Avidin and streptavidin both form homotetrameric complexes of
 noncovalently associated chains. Each chain forms a very strong and specific
 non-covalent complex with one molecule of biotin. The dimeric bacterial
 avidin sub-family members that bind biotin with high affinity exhibit a
 dimeric (1-4 dimer) rather than a tetrameric structure. The fibropellin
 avidin-like domain forms a homotetramer incapable of binding biotin.
