Template:STRUCTURE 3fdc Avidin
Avidin (Av) is a protein found in egg white which binds biotin (vitamin B7) with high affinity. This property makes it a powerful tool in various protein pull-down assays. Similar proteins are strepavidin (StrAv) from the bacterium Streptomyces avidinii, Rhizavidin (RhiAv) from Rhizobium etli, Xenavidin from frog, and the avidin-related proteins AVR2 and AVR4.
