Miscellaneousi

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.

Similar proteinsi

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into Uniref entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
