CC   -!- FUNCTION: Zeins are major seed storage proteins.
CC   -!- MISCELLANEOUS: The alpha zeins of 19 kDa and 22 kDa account for 70% of
CC       the total zein fraction. They are encoded by a large multigene family.
CC   -!- MISCELLANEOUS: Structurally, 22K and 19K zeins are composed of nine
CC       adjacent, topologically antiparallel helices clustered within a
CC       distorted cylinder. {ECO:0000250|UniProtKB:P04698}.
CC   -!- SIMILARITY: Belongs to the zein family. {ECO:0000305}.
