Figure 1
Assembly of the protein molecules in the monoclinic (a–c) and orthorhombic (d–f) crystal forms. Crystal structures are viewed along the c axis (a, d), a axis (b, e) and b axis (c, f). The secondary structures of NowGFP are represented as ribbons, while the unit cell of each crystal form is outlined in a black box. For the monoclinic form, molecules 1, 2, 3 and 4 are coloured blue, purple, light purple and light blue, respectively. For the orthorhombic form, molecules 1A, 2A, 3A, 4A, 1B, 2B, 3B and 4B are coloured blue, light blue, light purple, purple, yellow, light orange, light yellow and orange, respectively. |
