Streptavidin is not the only protein capable of binding to biotin with high affinity. Avidin is the other most notable biotin-binding protein. Originally isolated from egg yolk, avidin only has 30% sequence identity to streptavidin, but almost identical secondary, tertiary and quaternary structure. Avidin has a higher affinity for biotin (Kd ~ 10 M) but in contrast to streptavidin, avidin is glycosylated, positively charged, has pseudo-catalytic activity (avidin can enhance the alkaline …
