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.

 1-80 6.04e-14

type I phosphomannose isomerase in eukaryotes and bacteria, N-terminal cupin domain; This subfamily contains type I phosphomannose isomerase (PMI; E.C. 5.3.1.8; also known as mannose-6-phosphate isomerase) found in eukaryotes and some bacteria such as Salmonella enterica. PMI catalyzes the reversible isomerization of fructose-6-phosphate (F6P) and mannose-6-phosphate (M6P), the first committed step in the synthesis of mannosylated glycoproteins. The active site, located within the N-terminal jelly roll-like beta-barrel cupin fold, contains a single essential zinc atom and forms a deep, open cavity large enough to contain M6P or F6P. PMI type I also has a C-terminal beta-barrel fold which has diverged considerably from the N-terminal domain and is not included here. This subfamily contains an alpha helical domain that is found in eukaryotic and some prokaryotic PMIs but is not present in their archaeal counterparts. F6P is a substrate for glycolysis and gluconeogenesis, while M6P is a substrate for production of activated mannose donor guanosine 5'-diphosphate D-mannose, an important precursor of mannosylated biomolecules such as glycoproteins, bacterial exopolysaccharides and fungal cell wall components. PMI is also essential for survival, virulence and possibly pathogenicity of some bacteria and protozoan parasites, as well as for cell wall integrity of certain yeasts. Thus, PMI is a potential target against fungal infections causing serious illness or death.
