The chemical reactions involving any amino acid not found, or rarely found, in peptide linkage in proteins.

Catalysis of the transfer of a methyl group from S-adenosyl-L-methionine to an amino group of an arginine residue in a protein substrate.

The chemical reactions involving acetyl-CoA, a derivative of coenzyme A in which the sulfhydryl group is acetylated; it is a metabolite derived from several pathways (e.g. glycolysis, fatty acid oxidation, amino-acid catabolism) and is further metabolized by the tricarboxylic acid cycle. It is a key intermediate in lipid and terpenoid biosynthesis.

The formation from simpler components of acetyl-CoA, a derivative of coenzyme A in which the sulfhydryl group is acetylated.

Catalysis of the transfer of a hydroxyl group from 2-oxoglutarate to a prolyl residue in a collagen molecule.

Catalysis of the transfer of a methyl group from S-adenosyl-L-methionine to the epsilon-amino group of a lysine residue.

Catalysis of the reaction: ATP + D-glucose = ADP + D-glucose 6-phosphate.

Catalysis of the reaction: S-adenosyl-L-methionine + L-homocysteine = S-adenosyl-L-homocysteine + L-methionine.

Catalysis of the transfer of a methyl group from S-adenosyl-L-methionine to the epsilon-amino group of a lysine residue in a protein substrate.

Catalysis of the reaction: D-glucosamine 6-phosphate + H2O = D-fructose 6-phosphate + NH3.

Catalysis of the reaction: D-glucose 6-phosphate + NADP+ = D-glucono-1,5-lactone 6-phosphate + NADPH + H+.

Catalysis of the reaction: D-glucose 6-phosphate + H2O = D-glucose + phosphate.

Catalysis of the reaction: D-glucose 6-phosphate = D-fructose 6-phosphate.

Any process that modulates the frequency, rate or extent of rhodopsin gene activity. This includes transcriptional, translational, or posttranslational regulation.

Catalysis of the reaction: D-glucosyl-N-acylsphingosine + H2O = D-glucose + N-acylsphingosine.

The chemical reactions involving glycerol, 1,2,3-propanetriol, a sweet, hygroscopic, viscous liquid, widely distributed in nature as a constituent of many lipids.
