Short name: Glutelin

Overlapping homologous superfamilies


Family relationships



Glutelins are major storage proteins that aggregate in protein bodies in the endosperm of Zea mays (Maize) [PMID: 16668595, PMID: 3839076]. They comprise the second largest protein fraction in Maize endosperm [PMID: 3839076] (zeins being the largest), and show sequence similarities to other cereal storage proteins, such as gliadins, glutenins, hordeins, etc. Glutelins have a well-defined structure, including an N-terminal region containing varying numbers of repeats of the sequence PPPHVL [PMID: 16668595]; a Gln rich region that can be separated into 2 domains; and a Cys rich C-terminal domain that shows some regions of internal similarity. Glutelins have been shown [PMID: 3839076] to exhibit structural similarity to other cereal storage proteins, including a beta-reverse turn region which forms a loose helix-like domain.
