Search space is a different species (congener surrogate)
CONGENER SURROGATE. No genome, transcriptome or reference proteome exists for Zoanthus natalensis, so the dataset was searched against the transcriptome-derived proteome of a different species in the same genus, Zoanthus sociatus. Every identification is therefore conditional on cross-species sequence conservation and protein counts are not comparable with same-species searches. The identified sequences belong to Zoanthus sociatus transcript contigs.

Original study vs CnidoSite re-processing

Parameter As reported by the original study As applied by CnidoSite
Search engine PEAKS Studio 8.5 Comet 2026.01 + Percolator (Crux 4.2)
Sequence database in-house zoantharian contig database /mnt/sdb/jackie/cnidaria_omics/transcriptome_proteins/Zoanthus_sociatus.rep.pep
Surrogate: transcriptome-derived proteome of the congener Zoanthus sociatus (88,116 representative proteins). No proteome of Zoanthus natalensis is available.
Enzyme (not restated) trypsin (fully enzymatic, 2 termini)  ·  up to 2 missed cleavages
Precursor tolerance 10 ppm 10 ppm
Fragment tolerance 0.05 Da 0.02 Da
Fixed modification C+57.021464 (carbamidomethyl cysteine)
Variable modification M+15.9949,n+42.010565,NQ+0.984016 (methionine oxidation)
Decoy strategy Comet internal reversed (1:1)
False discovery rate 1% peptide and protein q ≤ 0.01 at the PSM level (Percolator q-values, target-decoy); protein level q ≤ 0.01
Quantification spectral counting (PSMs)
Contaminants cRAP appended and flagged; 10 contaminant proteins identified and excluded from the reported protein list
Gene mapping Peptides are reported against transcript sequences. This species has no CnidoSite gene models, so no protein links to a gene page.
