>gnl|CDD|48478 cd00714, GFAT, Glutamine amidotransferases class-II (Gn-AT)_GFAT-type. This domain is found at the N-terminus of glucosamine-6P synthase (GlmS, or GFAT in humans). The glutaminase domain catalyzes amide nitrogen transfer from glutamine to the appropriate substrate. In this process, glutamine is hydrolyzed to glutamic acid and ammonia. In humans, GFAT catalyzes the first and rate-limiting step of hexosamine metabolism, the conversion of D-fructose-6P (Fru6P) into D-glucosamine-6P using L-glutamine as a nitrogen source. The end product of this pathway, UDP-N-acetyl glucosamine, is a major building block of the bacterial peptidoglycan and fungal chitin.. Length = 215
