A novel chymotrypsin which is expressed in the midgut of the lepidopteran insect Spodoptera exigua is described. This enzyme, referred to as SeCT34, represents a novel class of chymotrypsins. Its amino-acid sequence shares common features of gut chymotrpysins, but can be clearly distinguished from other serine proteinases that are expressed in the insect gut. Most notable, SeCT34 contains a chymotrypsin activation site and the highly conserved motive DSGGP in the catalytic domain around the… CONTINUE READING
