FunFam 137188: Maltogenic alpha-amylase (Glucan 1,4-alpha-maltohy...

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
Glucan 1,4-alpha-glucosidase activity GO:0004339
Catalysis of the hydrolysis of terminal (1->4)-linked alpha-D-glucose residues successively from non-reducing ends of the chains with release of beta-D-glucose.
2 P36914 (/IMP) P69328 (/IMP)
4-alpha-glucanotransferase activity GO:0004134
Catalysis of the transfer of a segment of a (1->4)-alpha-D-glucan to a new 4-position in an acceptor, which may be glucose or (1->4)-alpha-D-glucan.
1 Q8RXD9 (/IDA)
4-alpha-glucanotransferase activity GO:0004134
Catalysis of the transfer of a segment of a (1->4)-alpha-D-glucan to a new 4-position in an acceptor, which may be glucose or (1->4)-alpha-D-glucan.
1 Q8RXD9 (/IGI)
Alpha-amylase activity GO:0004556
Catalysis of the endohydrolysis of (1->4)-alpha-D-glucosidic linkages in polysaccharides containing three or more alpha-(1->4)-linked D-glucose units.
1 G5EAT0 (/RCA)
Heteropolysaccharide binding GO:0010297
Interacting selectively and non-covalently with heteropolysaccharides. A heteropolysaccharide is a glycan composed of more than one type of monosaccharide residue.
1 Q8RXD9 (/IDA)

There are 8 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.
1 Q8RXD9 (/IMP)
Maltose catabolic process GO:0000025
The chemical reactions and pathways resulting in the breakdown of the disaccharide maltose (4-O-alpha-D-glucopyranosyl-D-glucopyranose).
1 Q8RXD9 (/IDA)
Carbohydrate metabolic process GO:0005975
The chemical reactions and pathways involving carbohydrates, any of a group of organic compounds based of the general formula Cx(H2O)y. Includes the formation of carbohydrate derivatives by the addition of a carbohydrate residue to another molecule.
1 G4NCF7 (/RCA)
Polysaccharide metabolic process GO:0005976
The chemical reactions and pathways involving a polysaccharide, a polymer of many (typically more than 10) monosaccharide residues linked glycosidically.
1 P69328 (/IMP)
Polysaccharide metabolic process GO:0005976
The chemical reactions and pathways involving a polysaccharide, a polymer of many (typically more than 10) monosaccharide residues linked glycosidically.
1 Q8RXD9 (/TAS)
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 G5EAT0 (/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 G5EAT0 (/RCA)
Starch catabolic process GO:0005983
The chemical reactions and pathways resulting in the breakdown of starch, the most important reserve polysaccharide in plants.

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 P69328 (/IDA)
Cytosol GO:0005829
The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes.
