the enzyme self-activates via autoprocessing, analysis using enzyme pro-forms with the N-terminal pro-sequence, the C-terminal pro-sequence or both pro-sequences as catalyst toward the pro-form with both N- and C-terminal pro-sequences, mechanism, overview. The stimulation occurs in two steps, with approximately 8fold stimulation by N-terminal cleavage, approximately 4fold stimulation by C-terminal cleavage, and 23fold stimulation by the cleavage of both termini, compared to the pro-form with both the N- and C-terminal pro-sequences. Such cleavage mainly occurs in a trans manner, i.e. the pro-form dimer cleaves the monomeric form. C-terminal cleavage is due to removal of its trans (inter-dimer) inhibitory effect |
