Crystallization and preliminary crystallographic data of the major albumin from Psophocarpus tetragonolobus (L.) DC.
نویسندگان
چکیده
The major seed albumin from Psophocarpus tetragonolobus (L.) DC, winged bean albumin 1, has been crystallized from ethanol as rhombic needles in a form suitable for high resolution x-ray crystallographic studies. The space group is I4(1)22 with cell parameters a = b = 95.6 A, and c = 86.0 A. Amino acid sequence homology between winged bean albumin 1 and legume 7 S globulins suggests that the former may be related to a structural domain of the 7 S globulins.

Condensed tannin (CT) or proanthocyanidin (PA) is a unique group of phenolic metabolite with high molecular weight with specific structure. It is reported that, the presence of high-CT in the legumes adversely affect the nutrients in the plant and impairs the digestibility upon consumption by animals. Winged bean (Psophocarpus tetragonolobus (L.) DC.) is one of the promising underutilized legum...

The lipids were extracted from the winged bean (Psophocarpus tetragonolobus) seed with water-saturated n-butanol. Lipids were separated into groups by preparative TLC on silica gel G. The amount of each lipid type was determined by analysis of the fatty acid constituents in each lipid type. Glyceride was the major lipid accounting for 89.6% of the total, followed by an unknown lipid 4%, free fa...
