Named by Vosloo et al. (34).
Conventional one-letter abbreviations are used for amino acids, except that O was used for ornithine. Lowercase one-letter abbreviations indicate d-amino acid residues. The sequence data obtained from Tang et al. (29) and the identities were confirmed by our group (34, 35).
Detected monoisotopic Mr of peptides determined from purified peptides using high-resolution time of flight-electrospray mass spectrometry (TOF-ESMS) (refer to Table S1 in the supplemental material).
