Functioni

Zeins are major seed storage proteins.

Miscellaneous

The alpha zeins of 19 kDa and 22 kDa account for 70% of the total zein fraction. They are encoded by a large multigene family.
Structurally, 22K and 19K zeins are composed of nine adjacent, topologically antiparallel helices clustered within a distorted cylinder.By similarity
