• PubMed Abstract: 
  

  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.
