Fistularia petimba

the purified preparation of the pI 5.7 isoenzyme gives an active 25 kDa subfragment by SDS-PAGE, together with a 15 kDa non-active subfragment. The enzyme is, thus, inferred to contain active subfragments together with the 15 kDa non-active fragments. Amino acid sequencing of the 25 kDa active subfragment reveals, together with the fully processed N-terminal sequence, two N-terminal peptides with extra Pro-Ser and Gly-Pro-Ser attached to it
