Figure 2. Coordination of BcsC’s C-terminus inside the channel and sequence conservation.

Figure 2.

(A) Interactions of BcsC’s C-terminus with residues forming the OM channel. Residues belonging to the C terminal extension are colored magenta, other residues are shown as ‘ball-and-sticks’ in gray for carbon atoms. Conserved residues likely to coordinate the translocating PE-cellulose are shown as ‘ball-and-sticks’ in gray and blue for the carbon atoms for polar and aromatic residues, respectively.

(B) Sequence conservation of BcsC based on conservation among PE-cellulose synthesizing cellulose synthases shown from blue (lowest) to red (highest) conservation. Calculated in CONSURF (Ashkenazy et al., 2010).
