GNPNAT1 produced in E.Coli is a single, non-glycosylated polypeptide chain containing 207 amino acids (1-184a.a.) and having a molecular mass of 23.1KDa.GNPNAT1 is fused to a 23 amino acid His-tag at N-terminus & purified by proprietary chromatographic techniques.
GNPNAT1 is a member of the GNA1 subfamily of the larger acetyltransferase family of proteins. GNPNAT1 is limited to the Golgi apparatus and the endosome. GNPNAT1 is vital for UDPGlcNAc biosynthesis pathway. GNPNAT1 catalyzes the synthesis of GlcNAc6P from AcCoA and GlcN6P, a step in the UDP-GlcNAc6P formation pathway.
