• PubMed Abstract: 
  

  Bovine pro-phospholipase A2 (Mr = 14,520), trigonal, P3(1)21, a = b = 46.5, c = 102.0 A, one molecule per asymmetric unit, lambda (Cu K alpha) = 1.54 A. The model incorporating 895 protein atoms, two molecules of 2-methyl-2,4-pentanediol, and 60 solvent water molecules, was refined by restrained least squares to a residual R = 0.194 for 14,667 reflections from 5 to 1.6 A resolution.
