RmlC-like cupin superfamily; This superfamily contains proteins similar to the RmlC (dTDP (deoxythymidine diphosphates)-4-dehydrorhamnose 3,5-epimerase)-like cupins. RmlC is a dTDP-sugar isomerase involved in the synthesis of L-rhamnose, a saccharide required for the virulence of some pathogenic bacteria. Cupins are a functionally diverse superfamily originally discovered based on the highly conserved motif found in germin and germin-like proteins. This conserved motif forms a beta-barrel fold found in all of the cupins, giving rise to the name cupin ('cupa' is the Latin term for small barrel). The active site of members of this superfamily is generally located at the center of a conserved barrel and usually includes a metal ion. The different functional classes in this superfamily include single domain bacterial isomerases and epimerases involved in the modification of cell wall carbohydrates, two domain bicupins such as the desiccation-tolerant seed storage globulins, and multidomain nuclear transcription factors involved in legume root nodulation.

 1-89 8.38e-36

cysteine dioxygenase, cupin domain; This family contains cysteine dioxygenase (CDO; EC 1.13.11.20), which catalyzes the conversion of cysteine to cysteine sulfinic acid, the first step in the biosynthesis of essential oxidized cysteine metabolites such as sulfate, hypotaurine, and taurine. CDO also plays an important role in the regulation of intracellular cysteine levels in mammals; CDO expression is altered in cancer cells, and abnormal or deficient CDO activity has been linked to Parkinson's disease, Alzheimer's disease, and rheumatoid arthritis. CDO is an iron-dependent thiol dioxygenase that uses molecular oxygen to oxidize the sulfhydryl group of cysteine to generate cysteine sulfinic acid. The CDO active site contains an amino acid-derived cofactor. These enzymes are found in prokaryotes as well as eukaryotes and belong to the cupin superfamily with a conserved "jelly roll-like" beta-barrel fold capable of homodimerization.

2-aminoethanethiol dioxygenase, cupin domain; This family contains 2-aminoethanethiol dioxygenase (also known as cysteamine dioxygenase, persulfurase or ADO; EC 1.13.11.19), which catalyzes the addition of two oxygen atoms to free cysteamine (2-aminoethanethiol) to form hypotaurine that subsequently oxidizes to taurine. These enzymes are found in prokaryotes as well as eukaryotes and belong to the cupin superfamily with a conserved "jelly roll-like" beta-barrel fold capable of homodimerization.
