چکیده

Small angle x-ray scattering and viscometric analyses of the alpha-zeins of maize in solution indicated that the molecules were asymmetric. Structure predictions of consensus sequences for the two classes of alpha-zeins, Z19 and Z22, were in good agreement with the alpha-helical contents determined by circular dichroism. Dimensions determined by small angle x-ray scattering and viscometry indicated a predominantly alpha-helical conformation. The data are discussed in relation to models for the solution conformation and to earlier models for alpha-zeins structure.

Genomics analysis of genes expressed in maize endosperm identifies novel seed proteins and clarifies patterns of zein gene expression.

We analyzed cDNA libraries from developing endosperm of the B73 maize inbred line to evaluate the expression of storage protein genes. This study showed that zeins are by far the most highly expressed genes in the endosperm, but we found an inverse relationship between the number of zein genes and the relative amount of specific mRNAs. Although alpha-zeins are encoded by large multigene familie...

A defective signal peptide in a 19-kD alpha-zein protein causes the unfolded protein response and an opaque endosperm phenotype in the maize De*-B30 mutant.

Defective endosperm* (De*)-B30 is a dominant maize (Zea mays) mutation that depresses zein synthesis in the developing endosperm. The mutant kernels have an opaque, starchy phenotype, malformed zein protein bodies, and highly increased levels of binding protein and other chaperone proteins in the endosperm. Immunoblotting revealed a novel alpha-zein protein in De*-B30 that migrates between the ...

RNA interference-mediated change in protein body morphology and seed opacity through loss of different zein proteins.

Opaque or nonvitreous phenotypes relate to the seed architecture of maize (Zea mays) and are linked to loci that control the accumulation and proper deposition of storage proteins, called zeins, into specialized organelles in the endosperm, called protein bodies. However, in the absence of null mutants of each type of zein (i.e. alpha, beta, gamma, and delta), the molecular contribution of thes...

Separation of alcohol-soluble proteins (zeins) from maize into three fractions by differential solubility.

The prolamin of maize (Zea mays L.), zein, was extracted from endosperm meal with 60% (v/v) 2-propanol/1% (v/v) 2-mercaptoethanol either directly or subsequent to extraction with 90% (v/v) 2-propanol. The zein extracted with 90% 2-propanol was essentially made up of 20 to 24 kilodalton polypeptides (alpha-zein) while that extractable with 60% 2-propanol/1% 2-mercaptoethanol contained, in additi...

A defective signal peptide tethers the floury-2 zein to the endoplasmic reticulum membrane.

The maize (Zea mays L.) floury-2 (fl2) mutation is associated with a general decrease in storage protein synthesis, altered protein body morphology, and the synthesis of a novel 24-kD alpha-zein storage protein. Unlike storage proteins in normal kernels and the majority of storage proteins in fl2 kernels, the 24-kD alpha-zein contains a signal peptide that would normally be removed during prote...
