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. : Pssm-ID: 380366 [Multi-domain] Cd Length: 104 Bit Score: 110.64 E-value: 1.02e-32

52-105 | 2.04e-06 | |||
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. Pssm-ID: 380343 [Multi-domain] Cd Length: 126 Bit Score: 43.70 E-value: 2.04e-06

36-108 | 1.36e-05 | |||
quercetinase, N- and C-terminal cupin domains; This family contains quercetinase (also known as quercetin 2,3-dioxygenase, 2,3QD, QDO and YxaG; EC 1.13.11.24), a mononuclear copper-dependent dioxygenase that catalyzes the cleavage of the flavonol quercetin (5,7,3',4'-tetrahydroxyflavonol) heterocyclic ring to produce 2-protocatechuoyl-phloroglucinol carboxylic acid and carbon monoxide. Bacillus subtilis quercetin 2,3-dioxygenase (QDO) is a homodimer that shows oxygenase activity with several divalent metals such as Mn2+, Co2+, Fe2+, and Cu2+, although the preferred one appears to be Mn2+. The dioxygen binds to the metal ion of the Cu-QDO-quercetin complex, yielding a Cu2+-superoxo quercetin radical intermediate, which then forms a Cu2+-alkylperoxo complex which then evolves into endoperoxide intermediate that decomposes to the product. Quercetinase is a bicupin with two tandem cupin beta-barrel domains, both of which are included in this alignment model. The pirins, which also belong to the cupin domain family, have been shown to catalyze a reaction involving quercetin and may have a function similar to that of quercetinase.

38-106 | 1.54e-05 | |||
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.

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.

18-103 | 2.58e-03 | |||
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. Pssm-ID: 380380 [Multi-domain] Cd Length: 93 Bit Score: 34.86 E-value: 2.58e-03
