Sodium L-pyroglutamate is an uncommon amino acid derivative in which the free amino group of glutamic acid cyclizes to form a lactam. Molecular Formula:C5H6NNaO3. Molecular Weight:151.09. It is found in many proteins including bacteriorhodopsin. N-terminal glutamine residues can spontaneously cyclize to become pyroglutamate.
This is one of several forms of blocked N-terminals which present a problem for N-terminal sequencing using Edman chemistry, which requires a free primary amino group not present in pyroglutamic acid. CAS Number:28874-51-3 The enzyme pyroglutamate aminopeptidase can restore a free N-terminus by cleaving off the pyroglutamate residue.
