Stabilization of the N-terminal β-strand by H bonding in T. maritima ferredoxin. β-Strand Lys2-Val5 forms a two-stranded β-sheet with β-strand Ile56-Glu59. The N-terminal β-strand is fixed to the protein core by three H bonds (gray dotted lines) to turn D: two bonds between Met1 and Thr39, and one bond between Val3 and Pro37.
