Structural and Functional Characteristics of Xenavidin, the First Frog Avidin from Xenopus Tropicalis.
Bmc Struct.Biol., 9:63-, 2009

PubMed Abstract: Avidins are proteins with extraordinarily high ligand-binding affinity, a property which is used in a wide array of life science applications. Even though useful for biotechnology and nanotechnology, the biological function of avidins is not fully understood. Here we structurally and functionally characterise a novel avidin named xenavidin, which is to our knowledge the first reported avidin from a frog.
