FunFam 80: Carotene epsilon-monooxygenase, chloroplastic

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
Carotene beta-ring hydroxylase activity GO:0010291
Catalysis of the reaction: a carotene + a reduced electron acceptor + O2 = C3-hydroxylated carotene + an oxidized electron acceptor + H2O. This is a general reaction to represent the C3 hydroxylation of the beta ring of a carotene.
 2 Q93VK5 (/IMP) Q93VK5 (/IMP)
Zeinoxanthin epsilon hydroxylase activity GO:0009974
Catalysis of the reaction: zeinoxanthin + NADPH + O2 + H+ = lutein + NADP+ + H2O. Adds a hydroxyl group to the epsilon ring of the alpha-carotene.
 1 Q6TBX7 (/IMP)

There are 2 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
Carotenoid biosynthetic process GO:0016117
The chemical reactions and pathways resulting in the formation of carotenoids, tetraterpenoid compounds in which two units of 4 isoprenoid residues joined head-to-tail are themselves joined tail-to-tail.
 3 Q6TBX7 (/IMP) Q93VK5 (/IMP) Q93VK5 (/IMP)
Xanthophyll biosynthetic process GO:0016123
The chemical reactions and pathways resulting in the formation of xanthophylls, oxygen-containing carotenoids.
 2 Q93VK5 (/IGI) Q93VK5 (/IGI)

There are 4 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.
 5 O23365 (/IDA) O23365 (/IDA) Q6TBX7 (/IDA) Q93VK5 (/IDA) Q93VK5 (/IDA)
Chloroplast envelope GO:0009941
The double lipid bilayer enclosing the chloroplast and separating its contents from the rest of the cytoplasm; includes the intermembrane space.
 5 O23365 (/IDA) O23365 (/IDA) Q6TBX7 (/IDA) Q93VK5 (/IDA) Q93VK5 (/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 O23365 (/IDA) O23365 (/IDA)
Chloroplast GO:0009507
A chlorophyll-containing plastid with thylakoids organized into grana and frets, or stroma thylakoids, and embedded in a stroma.
