They appear to have independently and convergently evolved an Asp/Ser/His catalytic triad, like that found in the trypsin serine proteases (see Pfam:PF00089). Structure is an alpha/beta fold containing a 7-stranded parallel beta sheet, order 2314567.

PF18463Proprotein convertase subtilisin-like/kexin type 9 C-terminal domain (PCSK9_C3)Proprotein convertase subtilisin-like/kexin type 9 C-terminal domainThis entry represents a subdomain found in the C-terminal cysteine/histidine-rich domain (CRD) of PCSK9 (also known as neural apoptosis-regulated convertase, NARC-1) [1].

PCSK9 has been shown to regulate circulating LDL-R levels by controlling LDL-R degradation. Furthermore, numerous mutations in the PCSK9 gene have been identified and associated with hypercholesterolemia (gain of function) or hypocholesterolemia (loss of function) [2]. The fully folded CRD, shows structural similarity to the resistin homotrimer, a small cytokine associated with obesity and diabetes. The C-terminal domain from PCSK9 consists of three, three-stranded beta-subdomains arranged in a pseudothreefold, and each of the subdomains in the CRD of PCSK9 consists of three structurally conserved disulfide bonds [1].

The subtilisin propeptides are known to function as molecular chaperones, assisting in the folding of the mature peptidase [1], but have also been shown to act as 'temporary inhibitors' [2].
