In the attached vancomycin chain-A structure (PDB 1AA5, 132 atoms), row 3 is the CA atom of residue 1 (MLU, the sequence N-terminus of this 7-residue backbone) and row 122 is the CA atom of residue 7 (3FG, the sequence C-terminus). Compute the distance between these two rows, and compare it to the whole-molecule maximum pairwise distance already established for this same chain (Dmax = 19.5698 angstrom, from the preceding question). Does this terminal-to-terminal distance alone describe the molecule's full spatial extent? Report the terminal distance in angstrom to four decimal places.

The attachment is the same complete chain-A structure used previously (S0002, 132 atoms). Coordinates are in angstrom (1 nm = 10 angstrom). Atom rows are numbered starting at 1, immediately after the two header lines. Row order matches the order in this attachment exactly; do not renumber or reorder atoms.
