Crystal structure of the N-acetylmannosamine kinase domain of GNE.
UDP-GlcNAc 2-epimerase/ManNAc 6-kinase, GNE, is a bi-functional enzyme that plays a key role in sialic acid biosynthesis.Mutations of the GNE protein cause sialurea or autosomal recessive inclusion body myopathy/Nonaka myopathy.GNE is the only human protein that contains a kinase domain belonging to the ROK (repressor, ORF, kinase) family.We solved
