Figure 1
Crystals and architecture of FABP. The ribbon representation displays the ten-stranded β-barrel fold of hFABP4 (PDB entry 7g0n, ligand-free, obtained from delipidated hFABP4) with the chain colored in a rainbow from the N-terminus to the C-terminus (marked). The cavity available for fatty acid or other ligand binding is shown as a gray volume of 540 Å3 (1.4 Å probe radius). Fig. 7[link](a) shows FABP4_5 in a similar orientation with a fatty acid bound. The scale bars for the different crystal forms are ∼0.4 mm.
