Putative active site of oligosaccharyltransferase comprising the two conserved motifs. (A) Sequence alignment of the region containing the known WWDYG motif and the newly found DK motif. An initial alignment was obtained with the Mafft algorithm (Katoh et al, 2005) in the program Jalview, and then was edited manually. (B) Close-up view of the putative active site, with the WWDYG motif in cyan (W511, W512, D513, Y514, and G515), and the DK motif in yellow (D571 and K574). Alternative possible side-chain directions of W512 and D513 in the absence of crystal packing effects are indicated by gray arrows.
