Figure 3From: A model of tripeptidyl-peptidase I (CLN2), a ubiquitous and highly conserved member of the sedolisin family of serine-carboxyl peptidasesSequences of the catalytic domains of CLN2. Complete sequences are shown for CLN2 from human, fugu, and zebrafish, together with the partial sequence of putative CLN2 in Xenopus tropicalis. Residues identical in all four enzymes are colored green and those similar are colored magenta. Active site residues are marked as in Figure 1.Back to article page
