PNGase, or N-glycanase 1, is a human gene encoded by NGLY1. It may also be known as: Peptide-N(4)-(N-acetyl-beta-glucosaminyl)asparagine amidase; hPNGase; Peptide:N-glycanase; asparagine amidase; CDG1V; PNG1. The encoded protein is an enzyme with an amino acid length of 654 and a mass of 74.4 kDa. Other isoforms may exist. PNGase is a member of the Transglutaminase-like superfamily, PNGase family. Homologs of this gene exist in other organisms, including: Mouse, Rat, Zebrafish, Frog, Chicken.
