  Curdlan II

Linkage : beta 1-4     

Space Group : P1?(The probable space group is P1, but the three strands of the triplex are close to P3 symmetry)

Unit Cell Dimensions (a, b, c in Å and α, β, γ in °)

(No values are displayed if no information is available or the value is zero)

a (Å) = 15.56 - b (Å) = 15.56 - c (Å) = 18.78 - γ (°) = 120.00

Helix Type : triplex of right-handed, sixfold helical chains in a hexagonal unit cell

Method(s) Used For Structure Determination : X-ray diffraction and stereochemical model refinement
