Fig. 2. Primary structure of CTPL1. cDNA sequence and deduced amino acid sequence
(standard: zymogen; bold: mature protease) of the M. sexta CTLP1.
Italic characters indicate the 5' and 3' untranslated regions of
the cDNA and the putative signal peptide for the secretory pathway of the
protein. Arrows mark the predicted cleavage sites of the signal peptidase and
trypsin.
