Fig. 1. Maximum likelihood analyses of the vertebrate preproendothelin amino acid
sequences. Following the WAG model of amino acid substitutions
(Whelan and Goldman, 2001) and
a gamma=1.023, there are three distinct groups of preproendothelins,
preproendothelin-1 (abbreviated as only EDN1 to save space),
preproendothelin-2 (EDN2) and preproendothelin-3 (EDN3). Numbers at nodes
represent the percent bootstrap (BS=500 replications). GenBank accession or
