Manually codon-aligned sequences (see supplemental File S4 at http://www.genetics.org/supplemental/) were used to determine selection pressure by SNAP (http://hcv.lanl.gov/content/hcv-db/SNAP/SNAP.html) (Korber 2000), a program that uses the method of Nei and Gojobori (1986). AgamITmD37E_Ele1.1 and TambITmD37E_Ele1 have intact coding sequences. AaegITmD37E_Ele4.1 has multiple frameshifts that were corrected by codon alignment. Most Vg-C sequences were obtained from Isoe (2000). See supplemental File S1 for methods.
SNAP does not give an output for dS when ps > 0.75, indicating substitution saturation.
