The supplied crambin structure's own SSBOND record pairs Cys16 and Cys26 as a disulfide bridge. Using the supplied SG (sulfur) coordinates, calculate the Cys16-Cys26 SG-SG distance. Report the distance in angstrom to three decimal places.

Coordinates are in angstrom (1 nm = 10 angstrom). XYZ atom rows are one-based after the two header lines. Use the supplied coordinate snapshot without optimization or periodic wrapping; this is a single deposited crystal model. Use S0007 only: the 6 Cys SG (sulfur) sites of 1CRN chain A, in residue order 3, 4, 16, 26, 32, 40 (rows 1-6 respectively). Row 3 = Cys16 SG; row 4 = Cys26 SG. Report the distance in angstrom to three decimals.
