We describe the sequence of a gene encoding a high molecular weight glutenin subunit (HMW-GS) expressed in the endosperm of the wheat relative Australopyrum retrofractum. Although the subunit has a similar primary structure to that HMW-GS genes present in other Triticeae species, its N-terminal domain is shorter, its central repetitive domain includes a unique dodecameric motif, and its C-terminal domain contain an extra cysteine residue. A phylogenetic analysis showed that the Glu-W1 gene is neither a true x- nor a true y-type subunit, although it is more closely related to the y-type genes present in the K and E genomes than to any other published HMW-GS gene. All these results indicated that this novel subunit may undergo a special evolutionary process different from other Triticeae species. A flour supplementation experiment showed that the Glu-W1 subunit has a negative effect on dough quality, which might be the result of interaction between the two closely placed cysteine residues in the C-terminal region.

D006109 Poaceae A large family of narrow-leaved herbaceous grasses of the order Cyperales, subclass Commelinidae, class Liliopsida (monocotyledons). Food grains (EDIBLE GRAIN) come from members of this family. RHINITIS, ALLERGIC, SEASONAL can be induced by POLLEN of many of the grasses.

D000595 Amino Acid Sequence The order of amino acids as they occur in a polypeptide chain. This is referred to as the primary structure of proteins. It is of fundamental importance in determining PROTEIN CONFORMATION.

D016415 Sequence Alignment The arrangement of two or more amino acid or base sequences from an organism or organisms in such a way as to align areas of the sequences sharing common properties. The degree of relatedness or homology between the sequences is predicted computationally or statistically based on weights assigned to the elements aligned between the sequences. This in turn can serve as a potential indicator of the genetic relatedness between the organisms.

D056625 Endosperm Nutritive tissue of the seeds of flowering plants that surrounds the EMBRYOS. It is produced by a parallel process of fertilization in which a second male gamete from the pollen grain fuses with two female nuclei within the embryo sac. The endosperm varies in ploidy and contains reserves of starch, oils, and proteins, making it an important source of human nutrition. Endosperms
D021122 Protein Subunits Single chains of amino acids that are the units of multimeric PROTEINS. Multimeric proteins can be composed of identical or non-identical subunits. One or more monomeric subunits may compose a protomer which itself is a subunit structure of a larger assembly. Protomers,Protein Subunit,Protomer,Subunit, Protein,Subunits, Protein
