a

Identification by comparison of determined mass using MS Reconstruct tool of Analyst 1.5.1 software of a LC-MS EMS Scan (1000 Da/s, scan sum = 2) with CyBase database using a mass tolerance of ± 1 Da.

b

Sequences from http://www.cybase.org.

c

Observed molecular weight.

d

Score providing evidence for the quality of the deconvoluted mass of a hit (≤ 1 Da) and criteria for identification: I=isotope distribution and C=charge state of all observed multi charged ions.

e

Theoretical masses calculated from amino acid sequences via free available mass calculator ProtParam tool from http://www.expasy.org and addition of exact mass of 24.063 Da to cyclization and folding.

f

Peptide mass tolerance: (theoretical mass-detected mass)-theoretical mass × 106 [ppm].

g

M=Möbius and B=bracelet.

h

Sequence from transcriptome-mining approach reported in (Koehbach et al., 2013).
