“…Intron structure Exon-intron boundaries are the same in phaseolin and conglycinin DNA sequences (Sun et al, 1981;Slightom et al, 1983;Doyle et al, 1986). Those five boundaries are, in the first unit, at the DE corner (residue 81), within the J ,3-strand (144), the H2-H3 corner (171); and in the second unit, the BC corner (248) and the 1a connection (335).…”

“…Sequence aligments imply structural similarity of 7S proteins from common bean, jack bean, soybean and pea seeds (Argos et al, 1985;Doyle et al, 1986;Gibbs et al, 1989). Insertions and deletions in these alignments are, with minor modifications, compatible with the phaseolin structure (see Figure 2).…”

“…There are two major types of storage proteins in legume seeds, known respectively as vicilins and legumins, which are distinguishable by their sedimentation coefficients (7S/11S), oligomeric organization (trimeric/hexameric) and polypeptide chain structure (single chain/disulphide-linked pair of chains) (Croy et al, 1982;Slightom et al, 1983Slightom et al, , 1985Higgins, 1984;Hirano et al, 1984;Marco et al, 1984;Doyle et al, 1986). Both types are found within an individual storage body (Graham and Gunning, 1970;Craig et al, 1980).…”

“…Analysis of amino acid sequence data from these two classes suggests that they may be evolutionarily and structurally related (Argos et al, 1985;Gibbs et al, 1989). Clear sequence relationships have been established within the classes (Doyle et al, 1986). Furthermore, a sequence motif common to legumins and vicilins (Argos et al, 1985) has been found to occur twice in vicilins, suggesting a repeated structural motif in vicilins (Gibbs et al, 1989).…”

Anisotropic phase rebuilding I Waste preventionGadsolid reactions of acetone vapor with neutral organic compounds, salts, or host crystals with strict exclusion of solvents are reported. This gas/solid technique largely avoids waste formation and saves resources, Starting hydrochlorides or hydrobromides are also synthesized by gadsolid techniques. Dihydrohalides of o-phenylenediamines give 1,5-benzodiazepines 3, aromatic and aliphatic 1,2-aminothiols (oaminothiophenol, penicillamines, cysteine) yield five-membered thiazolines and thiazolidines 7, 9, 11, 13. Virtually all carbonyl reagents of the primary amino type 14 give quantitatively the imino derivatives 15 and water. Salt formation may be helpful for increasing melting points and sometimes reactivity as in 8, 10, and 12 if surface passivation has to be overcome. In the case of solid 14 the free bases react equally well. Acetone (2) may be quantitatively removed from exhaust gases by using hydroxylaminium phosphate with formation of free acetone oxime at high flow rates. Inclusion of acetone into various hosts (17-20, but not 16) is more efficient by imbibition from the gas phase than by crystallization from acetone as the solvent. This advantage may be utilized for gas separations. Some further gases (vapors) coexist in imbibed clathrates whereas others do not. The mechanisms of the gadsolid reactions are elucidated using atomic force microscopy (AFM). Phase rebuildings involve anisotropic movements of molecules over large distances and the formation of characteristic features. In some cases surface hydrates catalyze the gadsolid reaction. Solid-state mechanisms for imbibition from the gas phase into host crystals with formation of clathrates are similar in nature to those of the covalent reactions. These results are correlated with known X-ray crystal structures where available.

The structure of the Al gene of Zea mays was determined by sequencing cDNA and genomic clones. The gene is composed of four exons and three short introns. The 40. 1-kd Al protein is an NADPH-dependent reductase. Germinal derivatives of the mutable al-ml allele with either recessive or wild-type phenotype have been isolated. Sequence analysis of these revertant alleles indicates that frame-shift mutations abolish Al gene function, whereas one additional amino acid within the protein sequence still allows wild-type gene expression. The presence of a second, promoter-like structure, upstream of the functional Al gene promoter is discussed with respect to its possible involvement in differential expression of the Al gene. The structure of the al-m2 8004, 3456 and 4412 alleles, featuring distinguishable phenotypes in the presence of Spm(En), was also determined. In all alleles the 1080-bp-long inhibitor (I) element is located 15 bp upstream of the CAAT box of the Al gene promoter. The unusual response of al-m2 alleles to trans-active signals of the Spm(En) element is discussed with respect to the position of the I inserts. Also presented are data on the structure and insertion sites of transposable elements determined by cloning and sequencing of the mutable al alleles al-mpapu, al-mr 102 and al-ml.
