 92-181 9.47e-25

XRE (Xenobiotic Response Element) family transcriptional regulators, C-terminal cupin domain; This family contains transcriptional regulators containing an N-terminal XRE (Xenobiotic Response Element) family helix-turn-helix (HTH) DNA-binding domain and a C-terminal cupin domain. Included in this family is Escherichia coli transcription factor SutR (YdcN) that plays a regulatory role in sulfur utilization; it regulates a set of genes involved in the generation of sulfate and its reduction, the synthesis of cysteine, the synthesis of enzymes containing Fe-S as cofactors, and the modification of tRNA with use of sulfur-containing substrates. This family belongs to the cupin superfamily with a conserved "jelly roll-like" beta-barrel fold capable of homodimerization.

 4-58 8.16e-06

putative zinc finger/helix-turn-helix protein, YgiT family; This model describes a family of predicted regulatory proteins with a conserved zinc finger/HTH architecture. The amino-terminal region contains a novel domain, featuring two CXXC motifs and occuring in a number of small bacterial proteins as well as in the present family. The carboxyl-terminal region consists of a helix-turn-helix domain, modeled by pfam01381. The predicted function is DNA binding and transcriptional regulation.

Helix-turn-helix; This large family of DNA binding helix-turn helix proteins includes Cro and CI. Within the protein Swiss:Q5F9C2, the full protein fold incorporates a helix-turn-helix motif, but the function of this member is unlikely to be that of a DNA-binding regulator, the function of most other members, so is not necessarily characteriztic of the whole family.

pectin degradation protein KdgF and related proteins, cupin domain; This family includes bacterial and archaeal pectin degradation protein KdgF that catalyzes the linearization of unsaturated uronates from both pectin and alginate, which are polysaccharides found in the cell walls of plants and brown algae, respectively, and represent an important source of carbon. These polysaccharides, mostly consisting of chains of uronates, can be metabolized by bacteria through a pathway of enzymatic steps to the key metabolite 2-keto-3-deoxygluconate (KDG). Pectin degradation is used by many plant-pathogenic bacteria during infection, and also, pectin and alginate can both represent abundant sources of carbohydrate for the production of biofuels. These proteins belong to the cupin superfamily with a conserved "jelly roll-like" beta-barrel fold.

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.

 117-177 2.14e-06

(S)-ureidoglycine aminohydrolase and related proteins, N-terminal cupin domain; This family includes the N-terminal cupin domain of (S)-ureidoglycine aminohydrolase (UGlyAH), an enzyme that converts (S)-ureidoglycine into (S)-ureidoglycolate and ammonia, providing the final substrate to the ureide pathway. The ureide pathway has recently been identified as the metabolic route of purine catabolism in plants and some bacteria where, uric acid, which is a major product of the early stage of purine catabolism, is degraded into glyoxylate and ammonia via stepwise reactions by seven different enzymes. Thus, this pathway has a possible physiological role in mobilization of purine ring nitrogen for further assimilation. This enzyme from Arabidopsis thaliana(AtUGlyAH) has been shown to bind a Mn2+ ion, via the C-terminal cupin domain, which acts as a molecular anchor to bind (S)-ureidoglycine, and its binding mode dictates the enantioselectivity of the reaction. The structure of AtUGlyAH shows a bi-cupin fold with a conserved "jelly roll-like" beta-barrel fold and an octameric functional unit. Several structural homologs of UGlyAH, including the Escherichia coli ortholog YlbA (also known as GlxB6), also exhibit similar features.

 125-171 7.98e-05

Bacillus subtilis bacilysin and related proteins, cupin domain; Bacilysin (BacB, also known as AerE in Microcystis aeruginosa) is a non-ribosomally synthesized dipeptide antibiotic that is produced and excreted by certain strains of Bacillus subtilis. It is an oxidase that catalyzes the synthesis of 2-oxo-3-(4-oxocyclohexa-2,5-dienyl)propanoic acid, a precursor to L-anticapsin. Each bacilysin monomer has two tandem cupin domains. It is active against a wide range of bacteria and some fungi. The antimicrobial activity of bacilysin is antagonized by glucosamine and N-acetyl glucosamine, indicating that bacilysin interferes with glucosamine synthesis, and thus, with the synthesis of microbial cell walls. AerE is thought to be involved in the formation of the 2-carboxy-6-hydroxyoctahydroindole (Choi) moiety found on all aeruginosin tetrapeptides, based on gene knock-out experiments. It is encoded by the aerE gene of the aerABCDEF aeruginosin biosynthesis gene cluster in Microcystis aeruginosa.

Helicobacter pylori HP0902 and related proteins, cupin domain; This family includes prokaryotic and archaeal proteins homologous to HP0902, a functionally uncharacterized protein from Helicobacter pylori and Spy1581, a protein of unknown function from Streptococcus pyogenes. These proteins demonstrate all-beta cupin folds that cannot bind metal ions due to the absence of a metal-binding histidine that is conserved in many metallo-cupins. HP0902 is able to bind bacterial endotoxin lipopolysaccharides (LPS) through its surface-exposed loops, where metal-binding sites are usually found in other metallo-cupins, and thus may have a putative role in H. pylori pathogenicity.

 126-182 6.82e-04

Streptomyces resistomycificus RemF cyclase and related proteins, cupin domain; RemF cyclase is a manganese-containing polyketide cyclase present in bacteria that is involved in the biosynthesis of resistomycin, the aromatic pentacyclic metabolite in Streptomyces resistomycificus. Structure of this enzyme shows a cupin fold with a conserved "jelly roll-like" beta-barrel fold that forms a homodimer. It contains an unusual octahedral zinc-binding site in a large hydrophobic pocket that may represent the active site. The zinc ion, coordinated to four histidine side chains and two water molecules, could act as a Lewis acid in the aldol condensation reaction catalyzed by RemF, reminiscent of class II aldolases.

Bacillus subtilis bacilysin and related proteins, N-terminal cupin domain; This model represents the N-terminal domain of bacilysin (BacB, also known as AerE in Microcystis aeruginosa), a non-ribosomally synthesized dipeptide antibiotic that is produced and excreted by certain strains of Bacillus subtilis. Bacilysin is an oxidase that catalyzes the synthesis of 2-oxo-3-(4-oxocyclohexa-2,5-dienyl)propanoic acid, a precursor to L-anticapsin. Each bacilysin monomer has two tandem cupin domains. It is active against a wide range of bacteria and some fungi. The antimicrobial activity of bacilysin is antagonized by glucosamine and N-acetyl glucosamine, indicating that bacilysin interferes with glucosamine synthesis, and thus, with the synthesis of microbial cell walls. AerE is thought to be involved in the formation of the 2-carboxy-6-hydroxyoctahydroindole (Choi) moiety found on all aeruginosin tetrapeptides, based on gene knock-out experiments. It is encoded by the aerE gene of the aerABCDEF Aeruginosin biosynthesis gene cluster in Microcystis aeruginosa. Proteins in this family belong to the cupin superfamily with a conserved "jelly roll-like" beta-barrel fold.

 121-177 4.99e-03

Phosphomannose isomerase type II, C-terminal cupin domain; This family includes the C-terminal cupin domain of mannose-6-phosphate isomerases (MPIs) which have been classified broadly into two groups, type I and type II, based on domain organization. This family contains type II phosphomannose isomerase (also known as PMI-GDP, phosphomannose isomerase/GDP-D-mannose pyrophosphorylase), a bifunctional enzyme with two domains that catalyze the first and third steps in the GDP-mannose pathway in which fructose 6-phosphate is converted to GDP-D-mannose. The N-terminal domain catalyzes the first and rate-limiting step, the isomerization from D-fructose-6-phosphate to D-mannose-6-phosphate, while the C-terminal cupin domain (represented in this alignment model) converts mannose 1-phosphate to GDP-D-mannose in the final step of the reaction. Although these two domains occur together in one protein in most organisms, they occur as separate proteins in certain cyanobacterial organisms. Also, although type I and type II MPIs have no overall sequence similarity, they share a conserved catalytic motif.
