There are five categories listed; the first four include positions present more than 95% of the time: (1) 99-100% nucleotide conservation; (2) 90-98% nucleotide conservation; (3) 80-89% nucleotide conservation; (4) less than 80% nucleotide conservation; (5) Positions present less than 95%.

1 Comparative results are shown by domain (All = all domains, I = Domain I, etc.) with the total number of residues in that domain listed in parentheses.

2 Percentages are listed (number/total) with the observed number of residues shown in parentheses.
