The chemical reactions involving guanine, guanine riboside, a nucleoside with a wide species distribution.

Interacting selectivzely with L-ascorbic acid, a six-carbon carbohydrate-like compound found in fruit and vegetables. It has vitamin C activity in humans and guinea pigs.

The chemical reactions involving 7-methylguanosine, a modified nucleoside that forms a cap at the 5'-terminus of eukaryotic mRNA.

Interacting lelectively with cobalamin (vitamin B12), a water-soluble vitamin characterized by possession of a corrin nucleus containing a cobalt atom.

Catalysis of the covalent attachment of ubiquitin-like proteins to lysine residues on the target protein. This function may be performed alone or in conjunction with an E3, ubiquitin-like protein ligase.

The breakdown into simpler components of any organic compound that is weakly basic in character and contains an amino or a substituted amino group. Amines are called primary, secondary, or tertiary according to whether one, two, or three carbon atoms are attached to the nitrogen atom.

small protein activating enzyme activity

Catalysis of the activation of small proteins, such as ubiquitin, through the formation of an ATP-dependent high-energy thioester bond.

The chemical reactions involving oligosaccharides, molecules with between two and (about) 20 monosaccharide residues connected by glycosidic linkages.

Catalysis of the activation of any small protein similar to ubiquitin, through the formation of an ATP-dependent high-energy thioester bond.

The formation from simpler components of oligosaccharides, molecules with between two and (about) 20 monosaccharide residues connected by glycosidic linkages.

The directed movement of carbohydrate into, out of, within or between cells. Carbohydrates are any of a group of organic compounds based of the general formula Cx(H2O)y.

The breakdown into simpler components of oligosaccharides, molecules with between two and (about) 20 monosaccharide residues connected by glycosidic linkages.

A change in state or activity of the organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of the perception of radiation.
