Prohormone convertases
The two proprotein convertases that specialize in the processing of the precursors of peptide hormones and neuropeptides are also known in the field as "prohormone convertases". Both "prohormone convertase" and "proprotein convertase" are interchangeably abbreviated as "PC". PC1 (also known as PC3 and commonly referred to as PC1/3) and PC2 are the primary enzymes involved in the processing of the bioactive peptides precursors at paired basic residues. PC1/3 and PC2 do not directly produce most neuropeptides and peptide hormones, but instead generate intermediates that contain C-terminal extensions of lysine and/or arginine residues; these are subsequently removed by carboxypeptidase E.
