There are three trinuclear copper clusters in the enzyme localized between domains 1 and 2 of each pair of neighbor chains. Three copper ions of type 1 lie close to one another near the surface of the central part of the trimer, and, effectively, a trimeric substrate binding site is formed in their vicinity. Laccase is a blue multi-copper enzyme that catalyzes the oxidation of a variety of organic substrates coupled to the reduction of molecular oxygen to water. It displays broad substrate specificity, catalyzing the oxidation of a wide variety of aromatic, notably phenolic, and inorganic substances. Laccase has been implicated in a wide spectrum of biological activities. Pssm-ID: 259910 [Multi-domain] Cd Length: 119 Bit Score: 84.63 E-value: 1.08e-19

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.

The second cupredoxin domain of the insect laccases similar to laccase 2 in Tribolium castaneum; This multicopper oxidase (MCO) subfamily includes the majority of insect laccases. One member is laccase 2 from Tribolium castaneum, which is required for beetle cuticle tanning. Laccase (polyphenol oxidase EC 1.10.3.2) is a blue multi-copper enzyme that catalyzes the oxidation of a variety of organic substrates coupled to the reduction of molecular oxygen to water. It displays broad substrate specificity, catalyzing the oxidation of a wide variety of aromatic - notably phenolic and inorganic substances. Laccase has been implicated in a wide spectrum of biological activities and, in particular, plays a key role in morphogenesis, development and lignin metabolism in fungi, plants and insects. Laccase is 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: 259951 [Multi-domain] Cd Length: 150 Bit Score: 46.07 E-value: 5.77e-06

Cupredoxin superfamily; Cupredoxins contain type I copper centers and are involved in inter-molecular electron transfer reactions. Cupredoxins are blue copper proteins, having an intense blue color due to the presence of a mononuclear type 1 (T1) copper site. Structurally, the cupredoxin-like fold consists of a beta-sandwich with 7 strands in 2 beta-sheets, which is arranged in a Greek-key beta-barrel. Some of these proteins have lost the ability to bind copper. The majority of family members contain multiple cupredoxin domain repeats: ceruloplasmin and the coagulation factors V/VIII have six repeats; laccase, ascorbate oxidase, spore coat protein A, and multicopper oxidase CueO contain three repeats; and nitrite reductase has two repeats. Others are mono-domain cupredoxins, such as plastocyanin, pseudoazurin, plantacyanin, azurin, rusticyanin, stellacyanin, quinol oxidase, and the periplasmic domain of cytochrome c oxidase subunit II.

The first cupredoxin domain of plant Ascorbate oxidase homologs; This subfamily is composed of plant pollen multicopper oxidase homologous to ascorbate oxidase. Ascorbate oxidase catalyzes the oxidation of ascorbic acid to dehydroascorbic acid. This multicopper oxidase (MCO) is found in cucurbitaceous plants such as pumpkin, cucumber, and melon. It can detect levels of ascorbic acid and eliminate it. The biological function of ascorbate oxidase is still not clear. Ascorbate oxidase belongs to MCO family which 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 1 of 3-domain MCOs contains part the trinuclear copper binding site, which is located at the interface of domains 1 and 3. This subfamily does not harbor trinuclear copper binding histidines. Pssm-ID: 259915 [Multi-domain] Cd Length: 118 Bit Score: 42.01 E-value: 9.69e-05

The third cupredoxin domain of uncharacterized multicopper oxidase; Multicopper Oxidases (MCOs) are multi-domain enzymes that are able to couple oxidation of substrates with reduction of dioxygen to water. MCOs oxidize their substrate by accepting electrons at a mononuclear copper centre and transferring them to a trinuclear copper centre which binds a dioxygen. The dioxygen, following the transfer of four electrons, is reduced to two molecules of water. These MCOs are capable of oxidizing a vast range of substrates, varying from aromatic to inorganic compounds such as metals. This subfamily of MCOs is composed of three cupredoxin domains. 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.

The first cupredoxin domain of coagulation factor VIII and similar proteins; Factor V is an essential coagulation protein with both pro- and anti-coagulant functions. Aberrant expression of human factor V can lead to bleeding or thromboembolic disease, which may be life-threatening. Bovine factor Va serves as the cofactor in the prothrombinase complex that results in a 300,000-fold increase in the rate of thrombin generation. Factor V is synthesized as a single polypeptide with six cupredoxin domains and a domain structure of 1-2-3-4-B-5-6-C1-C2, where 1-6 are cupredoxin domains, B is a domain with no known structural homologs and is dispensible for coagulant activity, and C are domains distantly related to discoidin protein-fold family members. Factor V has little activity prior to proteolytic cleavage by thrombin or FXa upon secretion. The resulting Factor Va is a heterodimer consisting of a heavy chain (1-2-3-4) and a light chain (5-6-C1-C2). This model represents the cupredoxin domain 1 of unprocessed Factor V or the heavy chain of Factor Va, and similar proteins including pseutarin C non-catalytic subunit.
