Enantioselective syntheses of (+)- and (−)-Phaseolinic acid

Tetrahedron Letters, 1996
Abstract (+)- and (−)-Phaseolinic acid ( 1 ) have been prepared in an enantioselective fashion from acetylenic acid 26 (or ent- 26 ) by a three step sequence involving lactonization, epimerization at C 3 , and oxidative cleavage. 26 was obtained as a single enantiomer using a Nicholas-Schreiber reaction.

Ein einfaches Verfahren zur Präparation von Phaseolin

Biochemie und Physiologie der Pflanzen, 1984
Summary An improved method is described for isolation and crystallization of phaseolin, the major storage protein of Phaseolus vulgaris L. The purification was achieved by extraction with ammonium sulphate followed by gel filtration on Sephadex G-25.

PHASEOLIN RFLP IN BEAN (PHASEOLUS VULGARIS) CULTIVARS

Journal of Food Biochemistry, 2000
A 0.5 kbp phaseolin gene fragment was used as a probe to study phaseolin restriction fragment length polymorphism (RFLP) in P. vulgaris cultivars. Results obtained from plants displaying type S and type T phaseolin suggest a genomic organization more variable than that previously described. This variability could be exploited to aid gene identification

Differential accumulation of four phaseolin glycoforms in transgenic tobacco

Plant Molecular Biology, 1991
An intron-less phaseolin gene was used to express phaseolin polypeptides in transgenic tobacco plants. The corresponding amounts of phaseolin immunoreactive polypeptides and mRNA were similar to those found in plants transformed with a bean genomic DNA sequence that encodes an identical beta-phaseolin subunit.

Concise syntheses of (+)- and (−)-methylenolactocins and phaseolinic acids

Tetrahedron Letters, 2008
Abstract (+)- and (−)-Methylenolactocins and phaseolinic acids are synthesized in four steps via asymmetric syn- and anti- aldol reactions of chiral N -succinyl-2-oxazolidinones using the same set of reagents.

Constitutive expression of the ?-phaseolin gene in different tissues of transgenic alfalfa does not ensure phaseolin accumulation in non-seed tissue

Plant Molecular Biology, 1992
Phaseolin is a glycoprotein that constitutes the major storage protein in bean seeds. The phaseolin gene promoters function in a seed-specific manner. In an attempt to understand if events following transcription of the gene also contribute to the seed-specific accumulation of the phaseolin protein, we studied the effect of substituting the ...

Proteolysis of Phaseolin in Relation to Its Structure

Journal of Agricultural and Food Chemistry, 1996
Phaseolin differs from other native legume proteins in that its hydrolysis by trypsin and pepsin stops after a limited number of peptides have been cleaved off. Concomitantly, trypsin splits each phaseolin subunit approximately into halves. The N-terminal sequencing of these final hydrolysis products of high molecular mass showed loss of a tetrapeptide

Phaseolin: its Past, Properties, Regulation and Future

1999
A vital foundation for civilization was the invention, apparently less than 20, 000 years ago, of crop cultivation. The realization that seeds could be collected and later sown to give new food plants permitted food to be grown and gathered at a given location for several years.

Extended map for the phaseolin linkage group ofPhaseolus vulgaris L

Theoretical and Applied Genetics, 1991
The linkage relationship of 11 bean (Phaseolus vulgaris) seed proteins (including phaseolin), 9 enzyme loci, and theP locus were analyzed in backcross and F2 progenies by use of the software package "Mapmaker." The progenies were obtained by crossing the breeding line 'XR-235-1' and the cultivar 'Calima'.
