Figure 6From: Structural insights from random mutagenesis of Campylobacter jejunioligosaccharyltransferase PglBStructural context of V432 and the MIV motif. (A) Alignment of bacterial PglB sequences in the vicinity of C. jejuni V432 and I571/V575. Numbering of ruler according to PglB C. lari , conserved residues shaded, residues shown in B marked by arrows. (B) Position of residues equivalent to PglB Cj V432, I571 and V575 in the crystal structure 3RCE of PglB C.lari [11] (red). Periplasmic domain in grey, transmembrane domain in dark green, bound D-Q-N-A-T- p-nitrophenylalanine acceptor peptide as atom-coloured ball-stick representation, Mg2+ ion as light-green sphere.Back to article page
