HMDB Protein ID HMDBP11782
Secondary Accession Numbers None
Name Heparan-alpha-glucosaminide N-acetyltransferase
  1. Transmembrane protein 76
Gene Name HGSNAT
Protein Type Unknown
Biological Properties
General Function Not Available
Specific Function Lysosomal acetyltransferase that acetylates the non-reducing terminal alpha-glucosamine residue of intralysosomal heparin or heparan sulfate, converting it into a substrate for luminal alpha-N-acetyl glucosaminidase.
