Figure 1
Crystals of PITP-α complexed with phosphatidylcholine. Two crystal forms are observed, occasionally in the same drop, as shown here. In rod-shaped crystals of form I, the four sides of the cross section of the elongated rod are of approximately the same dimension. An example is the longest crystal in this figure. The plate-shaped crystals of form II have one dimension of the cross section considerably shorter than the other. An example of this crystal form is directly above the longest (form I) crystal in the figure. |
