FunFam 86: Multicopper oxidase abr1

Please note: GO annotations are assigned to the full protein sequence rather than individual protein domains. Since a given protein can contain multiple domains, it is possible that some of the annotations below come from additional domains that occur in the same protein, but have been classified elsewhere in CATH.

There are 2 GO terms relating to "molecular function"

The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.
GO Term Annotations Evidence
Ferroxidase activity GO:0004322
Catalysis of the reaction: 4 Fe2+ + 4 H+ + O2 = 4 Fe3+ + 2 H2O.
1 Q09920 (/IMP)
Protein binding GO:0005515
Interacting selectively and non-covalently with any protein or protein complex (a complex of two or more proteins that may include other nonprotein molecules).
1 Q09920 (/IPI)

There are 5 GO terms relating to "biological process"

The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.
GO Term Annotations Evidence
Pigment metabolic process involved in developmental pigmentation GO:0043324
The chemical reactions and pathways involving biological pigments e.g. melanin, occurring as part of the development of an organ or organism.
3 A2R3T0 (/IMP) A2R3T0 (/IMP) A2R3T0 (/IMP)
Reductive iron assimilation GO:0033215
A process in which iron is solubilized by reduction from Fe3+ to Fe2+ via a cell surface reductase and subsequent transport of the iron across the membrane by iron uptake proteins.
1 Q09920 (/TAS)
Melanin biosynthetic process GO:0042438
The chemical reactions and pathways resulting in the formation of melanins, pigments largely of animal origin. High molecular weight polymers of indole quinone, they are irregular polymeric structures and are divided into three groups: allomelanins in the plant kingdom and eumelanins and phaeomelanins in the animal kingdom.
1 Q4WZB4 (/IMP)
Pigment biosynthetic process GO:0046148
The chemical reactions and pathways resulting in the formation of a pigment, any general or particular coloring matter in living organisms, e.g. melanin.
1 Q4WZB4 (/IMP)
Iron ion import across plasma membrane GO:0098711
The directed movement of iron ions from outside of a cell, across the plasma membrane and into the cytosol.
1 Q09920 (/IMP)

There are 2 GO terms relating to "cellular component"

The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.
GO Term Annotations Evidence
Endoplasmic reticulum GO:0005783
The irregular network of unit membranes, visible only by electron microscopy, that occurs in the cytoplasm of many eukaryotic cells. The membranes form a complex meshwork of tubular channels, which are often expanded into slitlike cavities called cisternae. The ER takes two forms, rough (or granular), with ribosomes adhering to the outer surface, and smooth (with no ribosomes attached).
1 Q09920 (/HDA)
High-affinity iron permease complex GO:0033573
A protein complex composed of a multicopper ferroxidase that oxidizes Fe(II) to Fe(III), and a ferric iron permease that transports the produced Fe(III) into the cell. In high-affinity transport the transporter is able to bind the solute even if it is only present at very low concentrations.
