The second Cupredoxin domain of the multicopper oxidase CueO, the cell division protein FtsP, and similar proteins; CueO is a multicopper oxidase (MCO) that is part of the copper-regulatory cue operon, which employs a cytosolic metalloregulatory protein CueR that induces expression of CopA and CueO under copper stress conditions. CueO is a periplasmic multicopper oxidase that is stimulated by exogenous copper(II). FtsP (also named SufI) is a component of the cell division apparatus. It is involved in protecting or stabilizing the assembly of divisomes under stress conditions. FtsP belongs to the multicopper oxidase superfamily but lacks metal cofactors. The protein is localized at septal rings and may serve as a scaffolding function. Members of this subfamily contain three cupredoxin domains and this model represents the second domain. Although MCOs have diverse functions, majority of them have three cupredoxin domain repeats that include one mononuclear and one trinuclear copper center. The copper ions are bound in several sites: Type 1, Type 2, and/or Type 3. The ensemble of types 2 and 3 copper is called a trinuclear cluster. MCOs oxidize their substrate by accepting electrons at a mononuclear copper center and transferring them to the active site trinuclear copper center. The cupredoxin domain 2 of 3-domain MCOs has lost the ability to bind copper. Pssm-ID: 259935 [Multi-domain] Cd Length: 146 Bit Score: 200.12 E-value: 9.63e-63

The second cupredoxin domain of fungal laccase, diphenol oxidase; Diphenol oxidase belongs to the laccase family. It catalyzes the initial steps in melanin biosynthesis from diphenols. Melanin is one of the virulence factors of infectious fungi. In the pathogenesis of C. neoformans, melanin pigments have been shown to protect the fungal cells from oxidative and microbicidal activities of host defense systems. Laccase is a blue multi-copper enzyme that catalyzes the oxidation of a variety aromatic - notably phenolic and inorganic substances coupled to the reduction of molecular oxygen to water. It has been implicated in a wide spectrum of biological activities and, in particular, plays a key role in morphogenesis, development and lignin metabolism. Laccase is a multicopper oxidase (MCO) composed of three cupredoxin domains that include one mononuclear and one trinuclear copper center. The copper ions are bound in several sites: Type 1, Type 2, and/or Type 3. The ensemble of types 2 and 3 copper is called a trinuclear cluster. MCOs oxidize their substrate by accepting electrons at a mononuclear copper center and transferring them to the active site trinuclear copper center. The cupredoxin domain 2 of 3-domain MCOs has lost the ability to bind copper. Pssm-ID: 259950 [Multi-domain] Cd Length: 164 Bit Score: 38.47 E-value: 2.51e-03

The third Cupredoxin domain of phenoxazinone synthase (PHS); Phenoxazinone synthase (PHS, 2-aminophenol:oxygen oxidoreductase) catalyzes the oxidative coupling of substituted o-aminophenols to produce phenoxazinones. PHS has been shown to participate in diverse biological functions such as spore pigmentation and biosynthesis of the antibiotic grixazone. PHS is a member of the laccase-like multicopper oxidase (MCO) family, which are able to couple oxidation of substrates with reduction of dioxygen to water. MCOs are capable of oxidizing a vast range of substrates, varying from aromatic compounds to inorganic compounds such as metals. Although the members of this family have diverse functions, majority of them have three cupredoxin domain repeats. The copper ions are bound in several sites: Type 1, Type 2, and/or Type 3. The ensemble of types 2 and 3 copper is called a trinuclear cluster. MCOs oxidize their substrate by accepting electrons at a mononuclear copper center and transferring them to the active site trinuclear copper center. The cupredoxin domain 3 of 3-domain MCOs contains the Type 1 (T1) copper binding site and part the trinuclear copper binding site, which is located at the interface of domains 1 and 3.

L-ascorbate oxidase, fungal type; This model describes a family of fungal ascorbate oxidases, within a larger family of multicopper oxidases that also includes plant ascorbate oxidases (TIGR03388), plant laccases and laccase-like proteins (TIGR03389), and related proteins. The member from Acremonium sp. HI-25 is characterized. Pssm-ID: 132431 [Multi-domain] Cd Length: 538 Bit Score: 39.05 E-value: 5.91e-03
