(a) The structure of the (100) face of m5U crystals (carbon, grey; oxygen, red; hydrogen, white; nitrogen, blue). The c-axis points into the plane of the paper. (b) Schematic representation: the growth rate along the a-axis is much faster than that along the b- or c-axis in a typical m5U crystal habit, while the growth along the a-axis is significantly inhibited in the presence of DAFP-1 becoming less than that along the b- or c-axis.
