Map and model of AaLS. (a) Sharpened map of AaLS at 1.42 Å resolution. (b) Density at 4.0σ of a masked-normalized Fo map output from Servalcat. (c) Overlay of the calculated Fo − Fc difference map at 4.0σ, (b) indicating positive density (green) and in some areas negative density (red). Hydrogen atoms were built into the model if the corresponding positive peaks were within 0.5 Å of the putative hydrogen atoms. (d) Examples of water molecules identified with accompanying hydrogen atoms. (e) Arginine 127 interacting with a phosphate ion which is a bi-product of lumazine synthesis. Potential hydrogen-bonding distances are indicated by dashed lines.
