Fig. 8. Pfam alignment of vasotab with representative Kazal type proteins. The residues in lower case are outstandingly different from the overall consensus. Residues identical in more than half of the sequences depicted are highlighted in grey. Cysteines are highlighted in black. Identity of sequences shown: Anemonia sulcata inhibitor of elastase (IELA_ANESU/4–48); Rhodnius prolixus thrombin inhibitor domain 1 and 2 (THBI_RHOPR/6–48 and 57–101); AGRI, agrin; IAC, acrosin inhibitor; FSA, follistatin; PE60, PEC60; IPST, pancreatic secretory trypsin inhibitor; IPSG, double headed protease inhibitor; IOV, ovomucoid inhibitor; QR1, quail retinal 1; SC1, secreted calcium binding 1 matrix glycoprotein; SPRC, secreted protein acidic and rich in cysteine, also called basement membrane protein 40.
