Isotope labeling delineates the β-sheet region in the synthetic fragment NH₂-WLARALIKRIAQMIPKGA*LA*VA*VA*Q-VCR-COOH of pulmonary surfactant SP-B. Top spectrum, native SP-B; middle spectrum, unlabeled synthetic peptide sequence; bottom spectrum, peptide with alanines labeled (*following labeled residues).
