| Abstract: | The projected structure of the vanadate-induced crystalline aggregates of Ca2+-ATPase molecules in isolated sarcoplasmic reticulum membranes has been determined. The molecules form tubular crystals with an oblique surface lattice having cell dimensions a = 65.9 A, b = 114.4 A and gamma = 77.9 degrees. The space group is P2. The crystalline tubules are formed through lateral aggregation of chains made up of dimers of Ca2+-ATPase molecules. |
