Table 2.

Percent similarities between catfish caspase 8 and its homologues. Percent similarities were determined by the MegAlign program within DNASTAR. Percent similarity = 100 × (matches/matches + mismatches + gaps). Protein alignment scores are affected by partial matches, derived from the PAM250 residue weight table

Species/gene	Percent similarity
Chicken caspase 1	18.7
Mouse caspase 1	19.9
Human caspase 2	20.4
Human caspase 4	19.9
Human caspase 5	19.6
Mouse caspase 12	15.8
Human caspase 9	24.8
Mouse caspase 9	22.3
Rat caspase 9	24.3
Xenopus caspase 9	23.2
Chicken caspase 8	30.0
Human caspase 8	30.5
Zebrafish caspase 8	25.6
