Table 2 Number of genes for different cysteine peptidase families found in insects

From: Expansion of cytochrome P450 and cathepsin genes in the generalist herbivore brown marmorated stink bug

Cysteine peptidasesa Drosophila melanogaster Tribolium castaneum Apis mellifera Bombyx mori Acyrthosiphon pisum Halyomorpha halys bcd
C1A (Papain): Cathepsin-B 1 11 1 1 34 ≥10 (20)
C1A (Papain): Cathepsin-L 9 13 1 2 2 ≥33 (67)
C2 (Calpain) 4 7 4 5 8 ≥11 (18)
C13 (Legumain) 0 0 0 0 5 7 (7)
C14 (Caspase) 7 8 5 4 6 ≥9 (10)
  1. aCysteine peptidase counts for each insect are based on latest gene annotation from Genbank, as assessed on 07/02/2017
  2. bThe ‘≥’ symbol indicates greater than or equal to
  3. cFigures in parentheses indicate total number of transcripts for a given gene family identified in H. halys transcriptome
  4. dThere was single transcript each for Cathepsin-J and Cathepsin-O identified in H. halys transcriptome, which are not indicated here
