Glutaminyl cyclase also known by the alternate name 'QC' catalyzes the conversion of glutaminyl residues towards pyroglutamyl formation in proteins. This enzyme weighs around 39 kDa and is distributed across various tissues with significant expression in the brain and secretory tissues. The active site of this enzyme facilitates the cyclization of N-terminal glutaminyl and glutamyl residues influencing protein stability and function.
Biological function summary

This enzyme modifies peptide hormones and neuropeptides by enhancing their activity or stability. Glutaminyl cyclase does not usually operate within large protein complexes. However its activity is critical for processing secretory proteins into their mature forms. Modifications by the enzyme often regulate peptide function making it an important player in cellular communication processes.

Pathways

Glutaminyl cyclase plays an important role in the neuroendocrine cascade and protein maturation pathways. This enzyme's activity connects with other proteins like hormone receptors affecting their downstream signaling processes. It also shares connections with proteins involved in the proteolytic processing pathway ensuring maturation and activation of peptide substrates.

Malfunction of glutaminyl cyclase associates with Alzheimer's disease and amyloidosis. The enzyme's activity influences accumulation of pyroglutamyl-modified proteins which have links to amyloid plaque formation in Alzheimer's disease. This connection involves amyloid-beta peptides where glutaminyl cyclase enhances the aggregation potential through N-terminal cyclization. Effective modulation of this enzyme’s activity might represent a therapeutic approach for related disorders.

常规信息

功能

Responsible for the biosynthesis of pyroglutamyl peptides. Has a bias against acidic and tryptophan residues adjacent to the N-terminal glutaminyl residue and a lack of importance of chain length after the second residue. Also catalyzes N-terminal pyroglutamate formation. In vitro, catalyzes pyroglutamate formation of N-terminally truncated form of APP amyloid-beta peptides [Glu-3]-amyloid-beta. May be involved in the N-terminal pyroglutamate formation of several amyloid-related plaque-forming peptides.

序列相似性

Belongs to the glutaminyl-peptide cyclotransferase family.
