L-Pyroglutamyl-L-phenylalanyl-L-leucine-p-nitroanilide (PFLNA)--a convenient chromogenic substrate for assay of thiol proteinases papain, ficin, and bromelain--was prepared by enzymatic synthesis with chymotrypsin as a catalyst. The thiol proteinases hydrolyze PFLNA with the liberation of p-nitroaniline, estimated spectrophotometrically by its absorbance at 410

Enzymes play a key role in insect-plant relationships. For a better understanding of these interactions, we analyzed Tuta absoluta digestive enzymes. Here, we describe a detailed protocol for the detection of trypsin and papain-like enzymes in Tuta absoluta larvae by

Papain

Papain is a cysteine protease of the peptidase C1 family. Papain consists of a single polypeptide chain with three disulfide bridges and a sulfhydryl group necessary for activity of the enzyme.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
