Figure 3. Sequence alignment of the three anSMEs putative clusters.
(A) anSMEcpe (CPF_0616 from Clostridium perfringens), anSMEbt (BT_0238 from Bacteroides thetaiotaomicron) and anSMEkp (AtsB from Klebsiella pneumoniae). Sequence positions in the proteins are in brackets. The conserved cysteinyl residues are indicated in black boxes and the other conserved residues are shadowed – UV visible absorption specta of reconstituted wild-type (WT) and M1, M2 and M3 variants of anSMEbt (B).
