MULTISPECIES: FdtA/QdtA family cupin domain-containing protein [Petrotoga]

Protein Classification

sugar 3,4-ketoisomerase( domain architecture ID 14448982)

sugar 3,4-ketoisomerase, such as Aneurinibacillus thermoaerophilus TDP-4-oxo-6-deoxy-alpha-D-glucose-3,4-oxoisomerase (FdtA), which mediates the isomerization of dTDP-6-deoxy-D-xylohex-4-ulose into dTDP-6-deoxy-D-xylohex-3-ulose in the biosynthesis of dTDP-3-acetamido-3,6-dideoxy-alpha-D-galactose, a glycan chain of the S-layer

 4-121 1.14e-59

sugar 3,4-ketoisomerase QdtA and related proteins, cupin domain; This family includes cupin domains of several bacterial proteins homologous to sugar 3,4-ketoisomerases. Thermoanaerobacterium thermosaccharolyticum QdtA catalyzes a key step in the biosynthesis of these sugars, the conversion of thymidine diphosphate (dTDP)-4-keto-6-deoxyglucose to dTDP-3-keto-6-deoxyglucose. In Aneurinibacillus thermoaerophilus, TDP-4-oxo-6-deoxy-alpha-D-glucose-3,4-oxoisomerase (also known as FdtA) is involved in the biosynthesis of dTDP-Fucp3NAc (3-acetamido-3,6-dideoxy-alpha-d-galactose), which is part of the repeating units of the glycan chain in the S-layer. Shewanella denitrificans bifunctional ketoisomerase/N-acetyltransferase (also known as FdtD) is involved in the third and fifth steps in the production of 3-acetamido-3,6-dideoxy-alpha-d-galactose or Fuc3NAc; the C-terminal cupin domain harbors the active site responsible for the isomerization reaction. Proteins in this family belong to the cupin superfamily with a conserved "jelly roll-like" beta-barrel fold capable of homodimerization.
