Scalar architecture of N-mannan fibrils. A. Dimensions of the N-mannan fibrils calculated from 16 discrete and intact mannan fibrils in our 3D cell wall model. The total fibril length (range), branch length (range), inter-branch length (mean) and branch angle (mean) are indicated (see Fig. S3 for explanation of the measurements). B. Scalar architecture of C. albicans N-mannan. The α(1,6)-mannose backbone is calculated to be between 74 and 194 mannose residues long, with the side branches varying in length from 10 − 45 mannose residues and emerging from opposite sides of the α(1,6)-backbone every 6–12 (mean: 10) mannose residues. Coloured hexagons represent specific linkages between sugar residues, as indicated.
