Figure 1

(a) Stereoview of the SauLigA structure. Subdomain 1a is shown in orange and subdomain 1b in cyan. NMN (green) and AMP (magenta) are positioned from the crystal structure of the EfaLigA–NAD complex (Gajiwala & Pinko, 2004 ▶). The labels N and C indicate the locations of the N- and C-termini. (b) A structure-based sequence alignment of SauLigA subdomain 1b (Sau) with those from En. faecalis (Efa), M. tuberculosis (Mtu), B. stearothermophilus (Bst), E. coli (Eco) and T. filiformis (Tfi). Secondary-structure elements of SauLigA are represented by ‘noodles’ (α-helices) and arrows (β-strands). They are colored blue for helices and orange for strands. Identical residues are highlighted in magenta. The conserved motifs are boxed in black. Every 20th residue is indicated by a black dot.
