FunFam 4: Proprotein convertase type 2

There are 1 EC terms in this cluster

Please note: EC annotations are assigned to the full protein sequence rather than individual protein domains. Since a given protein can contain multiple domains, it is possible that some of the annotations below come from additional domains that occur in the same protein, but have been classified elsewhere in CATH.

Note: The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.

EC Term Annotations Evidence
Proprotein convertase 2. [EC: 3.4.21.94]
Release of protein hormones and neuropeptides from their precursors, generally by hydrolysis of -Lys-Arg-|- bonds.
  • A calcium dependent enzyme, maximally active at about pH 5.5.
  • Specificity is broader than that of prohormone convertase 1.
  • Substrates include pro-opiomelanocortin, proenkephalin, prodynorphin, proinsulin and proluteinizing-hormone-releasing hormone.
  • Unlike prohormone convertase 1, does not cleave prorenin or prosomatostatin.
  • 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 1.
  • Belongs to peptidase family S8.
