FunFam 3: Probable alpha-glucosidase (Maltase)

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 5 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.
3 Q5B3N7 (/RCA) Q5B3N7 (/RCA) Q5B3N7 (/RCA)
Maltose alpha-glucosidase activity GO:0032450
Catalysis of the reaction: alpha-maltose + H2O = 2 alpha-D-glucose.
3 A0A1D8PP39 (/IDA) A0A1D8PP39 (/IDA) Q9P6J3 (/IDA)
Sucrose alpha-glucosidase activity GO:0004575
Catalysis of the reaction: sucrose + H2O = alpha-D-glucose + beta-D-fructose.
2 A0A1D8PUB9 (/IDA) Q9P6J3 (/IDA)
Dextrin alpha-glucosidase activity GO:0044653
Catalysis of the reaction: dextrin + H2O = alpha-D-glucose.

There are 9 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
Maltose metabolic process GO:0000023
The chemical reactions and pathways involving the disaccharide maltose (4-O-alpha-D-glucopyranosyl-D-glucopyranose), an intermediate in the catabolism of glycogen and starch.
3 Q5B3N7 (/RCA) Q5B3N7 (/RCA) Q5B3N7 (/RCA)
Sucrose catabolic process GO:0005987
The chemical reactions and pathways resulting in the breakdown of sucrose, the disaccharide fructofuranosyl-glucopyranoside.
2 A0A1D8PP39 (/IEP) A0A1D8PP39 (/IEP)
Starch metabolic process GO:0005982
The chemical reactions and pathways involving starch, the most important reserve polysaccharide in plants. It is a glucan consisting of two components, amylose and amylopectin, which are both glucose homopolymers. Starch is synthesized as a temporary storage form of carbon and can be catabolized to produce sucrose.
1 C8V523 (/IEP)
Sucrose catabolic process GO:0005987
The chemical reactions and pathways resulting in the breakdown of sucrose, the disaccharide fructofuranosyl-glucopyranoside.
1 A0A1D8PUB9 (/IDA)
Cellular response to starvation GO:0009267
Any process that results in a change in state or activity of a cell (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of deprivation of nourishment.
1 A0A1D8PUB9 (/IMP)
Filamentous growth GO:0030447
The process in which a multicellular organism, a unicellular organism or a group of unicellular organisms grow in a threadlike, filamentous shape.
1 A0A1D8PUB9 (/IMP)
Filamentous growth of a population of unicellular organisms in response to starvation GO:0036170
The process in which a group of unicellular organisms grow in a threadlike, filamentous shape in response to deprivation of nourishment.
1 A0A1D8PUB9 (/IMP)
Filamentous growth of a population of unicellular organisms in response to biotic stimulus GO:0036180
The process in which a group of unicellular organisms grow in a threadlike, filamentous shape in response to a biotic (living) stimulus.
1 A0A1D8PUB9 (/IMP)
Cellular polysaccharide catabolic process GO:0044247
The chemical reactions and pathways resulting in the breakdown of polysaccharides, polymers of many (typically more than 10) monosaccharide residues linked glycosidically, as carried out by individual cells.

There are 3 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
Extracellular region GO:0005576
The space external to the outermost structure of a cell. For cells without external protective or external encapsulating structures this refers to space outside of the plasma membrane. This term covers the host cell environment outside an intracellular parasite.
1 A0A1D8PUB9 (/IDA)
Nucleus GO:0005634
A membrane-bounded organelle of eukaryotic cells in which chromosomes are housed and replicated. In most cells, the nucleus contains all of the cell's chromosomes except the organellar chromosomes, and is the site of RNA synthesis and processing. In some species, or in specialized cell types, RNA metabolism or DNA replication may be absent.
1 Q9P6J3 (/HDA)
Cytosol GO:0005829
The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes.
