Pyroglutamate
Amidation
N-terminus is a pyroglutamic acid. C-terminal amidation. The N-terminus of Pen-3b (I10V) and Pen-3c (P14 deleted) may be Q or pyroglutamic acid. Structure: It contains a Pro-rich domain (PRD) from residue 10 to 28, which is disordered. The cysteine-rich domain (CRD: residues 29-58) displays a folded structure (helix: 41-50; Cys32-Cys47; Cys48-Cys55; Cys36-Cys54). It is proposed that a cooperative interaction between the PRD and CRD domains is important for activity (J Biol Chem 2003; 278: 36859-67)
