Fig 1. Recombinant proCrp4 deletion variant peptides prepared by site-directed mutagenesis.
The primary structures of the recombinant peptides prepared and assayed in this study are aligned. Lines shown in (Δ44–58)-proCrp4 and (Δ44–53)-proCrp4 sequences indicate the residue positions deleted in the truncated variants. MMP-7 cleavage sites are indicated by arrows.
