ENZYME entry: EC 3.4.21.93
Accepted Name |
Proprotein convertase 1.
|
Alternative Name(s) |
NEC 1. |
Neuroendocrine convertase 1. |
PC1. |
Prohormone convertase I. |
Reaction catalysed |
Release of protein hormones, neuropeptides and renin from their precursors, generally by hydrolysis of -Lys-Arg-|- bonds |
Comment(s) |
- 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.
