Enzyme Information

3.4.21.93
Proprotein convertase 1.
based on mapping to UniProt P63239
Release of protein hormones, neuropeptides and renin from their precursors, generally by hydrolysis of -Lys-Arg-|- bonds.
-!- A calcium dependent enzyme, maximally active at about pH 5.5. -!- Substrates include pro-opiomelanocortin, prorenin, proenkephalin, prodynorphin, prosomatostatin and proinsulin. -!- Unlike prohormone convertase 2, does not cleave proluteinizing- hormone-releasing hormone. -!- Usually processing of prodynorphin occurs at a bond in which P2 is Thr. -!- Present in the regulated secretory pathway of neuroendocrine cells, commonly actin co-operatively with prohormone convertase 2. -!- Belongs to peptidase family S8.
