FunFam 83: Plastocyanin

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
Protein domain specific binding GO:0019904
Interacting selectively and non-covalently with a specific domain of a protein.
2 P42699 (/IPI) P42699 (/IPI)
Electron transporter, transferring electrons from cytochrome b6/f complex of photosystem II activity GO:0046028
Enables the directed movement of electrons from the cytochrome b6/f complex of photosystem II.
2 P42699 (/IGI) P42699 (/IGI)

There are 3 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
Negative regulation of translation GO:0017148
Any process that stops, prevents, or reduces the frequency, rate or extent of the chemical reactions and pathways resulting in the formation of proteins by the translation of mRNA or circRNA.
2 P42699 (/IMP) P42699 (/IMP)
Response to copper ion GO:0046688
Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a copper ion stimulus.
2 P42699 (/IEP) P42699 (/IEP)
Copper ion homeostasis GO:0055070
Any process involved in the maintenance of an internal steady state of copper ions within an organism or cell.
2 P42699 (/IMP) P42699 (/IMP)

There are 6 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
Chloroplast GO:0009507
A chlorophyll-containing plastid with thylakoids organized into grana and frets, or stroma thylakoids, and embedded in a stroma.
3 P11490 (/IDA) P42699 (/IDA) P42699 (/IDA)
Thylakoid GO:0009579
A membranous cellular structure that bears the photosynthetic pigments in plants, algae, and cyanobacteria. In cyanobacteria thylakoids are of various shapes and are attached to, or continuous with, the plasma membrane. In eukaryotes they are flattened, membrane-bounded disk-like structures located in the chloroplasts; in the chloroplasts of higher plants the thylakoids form dense stacks called grana. Isolated thylakoid preparations can carry out photosynthetic electron transport and the associated phosphorylation.
3 P11490 (/IDA) P42699 (/IDA) P42699 (/IDA)
Thylakoid lumen GO:0031977
The volume enclosed by a thylakoid membrane.
3 P11490 (/IDA) P42699 (/IDA) P42699 (/IDA)
Chloroplast thylakoid GO:0009534
Sac-like membranous structures (cisternae) in a chloroplast combined into stacks (grana) and present singly in the stroma (stroma thylakoids or frets) as interconnections between grana. An example of this component is found in Arabidopsis thaliana.
2 P42699 (/IDA) P42699 (/IDA)
Chloroplast stroma GO:0009570
The space enclosed by the double membrane of a chloroplast but excluding the thylakoid space. It contains DNA, ribosomes and some temporary products of photosynthesis.
2 P42699 (/IDA) P42699 (/IDA)
Plastid thylakoid membrane GO:0055035
The lipid bilayer membrane of any thylakoid within a plastid.
