FunFam 6: Alpha-glucosidase 1

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 4 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
Alpha-1,4-glucosidase activity GO:0004558
Catalysis of the hydrolysis of terminal, non-reducing alpha-(1->4)-linked alpha-D-glucose residues with release of alpha-D-glucose.
1 O04931 (/IMP)
Xylan 1,4-beta-xylosidase activity GO:0009044
Catalysis of the hydrolysis of (1->4)-beta-D-xylans so as to remove successive D-xylose residues from the non-reducing termini.
1 Q9S7Y7 (/IDA)
Alpha-L-arabinofuranosidase activity GO:0046556
Catalysis of the hydrolysis of terminal non-reducing alpha-L-arabinofuranoside residues in alpha-L-arabinosides.
1 Q9S7Y7 (/IDA)
Xyloglucan 1,6-alpha-xylosidase activity GO:0080176
Catalysis of the hydrolysis of xyloglucan side chains so as to remove unsubstituted D-xylose residues attached to the glucose located at the non-reducing terminus.

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
Xyloglucan metabolic process GO:0010411
The chemical reactions and pathways involving xyloglucan, the cross-linking glycan composed of (1->4)-beta-D-glucan backbone substituted at regular intervals with beta-D-xylosyl-(1->6) residues, which is present in the primary cell wall of most higher plants.
1 Q9S7Y7 (/IMP)
Xylan catabolic process GO:0045493
The chemical reactions and pathways resulting in the breakdown of xylan, a polymer containing a beta-1,4-linked D-xylose backbone.
1 Q9S7Y7 (/IDA)
Response to cadmium ion GO:0046686
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 cadmium (Cd) ion stimulus.
1 Q9S7Y7 (/IEP)

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
Plant-type cell wall GO:0009505
A more or less rigid stucture lying outside the cell membrane of a cell and composed of cellulose and pectin and other organic and inorganic substances.
2 Q9LYF8 (/IDA) Q9S7Y7 (/IDA)
Plasmodesma GO:0009506
A fine cytoplasmic channel, found in all higher plants, that connects the cytoplasm of one cell to that of an adjacent cell.
2 F4J6T7 (/IDA) Q9S7Y7 (/IDA)
Apoplast GO:0048046
The cell membranes and intracellular regions in a plant are connected through plasmodesmata, and plants may be described as having two major compartments: the living symplast and the non-living apoplast. The apoplast is external to the plasma membrane and includes cell walls, intercellular spaces and the lumen of dead structures such as xylem vessels. Water and solutes pass freely through it.
2 Q9LYF8 (/IDA) Q9S7Y7 (/IDA)
Cell wall GO:0005618
The rigid or semi-rigid envelope lying outside the cell membrane of plant, fungal, most prokaryotic cells and some protozoan parasites, maintaining their shape and protecting them from osmotic lysis. In plants it is made of cellulose and, often, lignin; in fungi it is composed largely of polysaccharides; in bacteria it is composed of peptidoglycan; in protozoan parasites such as Giardia species, it's made of carbohydrates and proteins.
1 Q9S7Y7 (/IDA)
Vacuole GO:0005773
A closed structure, found only in eukaryotic cells, that is completely surrounded by unit membrane and contains liquid material. Cells contain one or several vacuoles, that may have different functions from each other. Vacuoles have a diverse array of functions. They can act as a storage organelle for nutrients or waste products, as a degradative compartment, as a cost-effective way of increasing cell size, and as a homeostatic regulator controlling both turgor pressure and pH of the cytosol.
1 Q9LYF8 (/IDA)
Chloroplast GO:0009507
A chlorophyll-containing plastid with thylakoids organized into grana and frets, or stroma thylakoids, and embedded in a stroma.
