Figure 4From: Ancestry and evolution of a secretory pathway serpinC-terminal sequences of neuroserpin orthologs from deuterostomes and serpin Spn-1 from Nematostella vectensis. The numbering of amino acids refers to human α1-antitrypsin (top). Amino acids flanking the (putative) scissile bond are marked in turquoise, and the P1 position is indicated. Residues conserved in at least 70% of sequences are reproduced in white-on-black.Back to article page
