... of what the question is. Right now you appear to be asking what enzyme converts a dipeptide (a chain of 2 amino acids - unless you mean 2 longer peptides associated in some way like s-s bonds) to a secretOry or secreted peptide (first means that the peptide is helping secretion to happen, second, ...

... and with factor Xa site). Both proteases seem to work, but both show some nonspecificity. I use tricine sds gel, that is for visualising small peptides, but I don’t get a band at the needed position. The same result is with MALDI TOF. Maybe the concentratoin of product is too low to visualise ...
