Cysteine proteinases from the Caricaceae belong to the C1 family of the CA clan and display papain-like structured, the archetype enzyme for this group of proteins. Carica candamarcensis, also named Vasconcellea cundinamarcensis, a member of Caricaceae family common to many areas in South America, contains cysteine proteinases with proteolytic activity five to eight-fold higher than those from latex of Carica papaya. The cysteine protease CMS2MS2 from C. candamarcensis latex has been shown to enhance proliferation of L929 fibroblast and to activate the extracellular signal-regulated protein kinase (ERK). In this study, the cDNA cloning, expression and evaluation of biological activity of a CMS2MS2-like protein from C. candamarcensis is reported. The 650 bp fragment was cloned in bacteria and the DNA sequence confirmed a cysteine-proteinase similar to CMS2MS2. The recombinant protein is 30 kDa, induces a mitogenic response, and enhances ERK1/2 phosphorylation, like the non-recombinant enzyme, but lacks either amidase or caseinolytic activity. The mitogenic activity of this protein and its lack of proteolytic activity underscore a potential for use in wound healing treatment.
