The chemical reactions and pathways involving beta-alanine (3-aminopropanoic acid), an achiral amino acid and an isomer of alanine. It occurs free (e.g. in brain) and in combination (e.g. in pantothenate) but it is not a constituent of proteins.

The chemical reactions and pathways involving amino acids, carboxylic acids containing one or more amino groups, as carried out by individual cells.

The chemical reactions and pathways resulting in the formation of 4-hydroxyproline, C5H9NO3, a derivative of the amino acid proline.

The chemical reactions and pathways resulting in the breakdown of L-lysine into other compounds, including glutarate, by acetylation.

The chemical reactions and pathways resulting in the breakdown of L-lysine, the L-enantiomer of (S)-2,6-diaminohexanoic acid.

The chemical reactions and pathways resulting in the breakdown of L-lysine into other compounds, including acetyl-CoA.

OBSOLETE. Any constituent part of the cytoskeleton, a cellular scaffolding or skeleton that maintains cell shape, enables some cell motion (using structures such as flagella and cilia), and plays important roles in both intra-cellular transport (e.g. the movement of vesicles and organelles) and cellular division. Includes constituent parts of intermediate filaments, microfilaments, microtubules, and the microtrabecular lattice.

The chemical reactions and pathways resulting in the breakdown of L-lysine into other compounds, including acetate.

OBSOLETE. Any constituent part of the Golgi apparatus, a compound membranous cytoplasmic organelle of eukaryotic cells, consisting of flattened, ribosome-free vesicles arranged in a more or less regular stack.

The chemical reactions and pathways resulting in the breakdown of D-lysine, the D-enantiomer of lysine; i.e. (2R)-2,6-diaminohexanoic acid.

The chemical reactions and pathways involving D-lysine, the D-enantiomer of lysine; i.e. (2R)-2,6-diaminohexanoic acid.

The chemical reactions and pathways resulting in the breakdown of lysine, 2,6-diaminohexanoic acid.

OBSOLETE. Any constituent part of the endoplasmic reticulum, 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 chemical reactions and pathways involving L-lysine, the L-enantiomer of (S)-2,6-diaminohexanoic acid, i.e. (2S)-2,6-diaminohexanoic acid.

OBSOLETE. Any constituent part of cytoplasmic vesicle, a vesicle formed of membrane or protein, found in the cytoplasm of a cell.

The chemical reactions and pathways involving D-amino acids, the D-enantiomers of amino acids.

OBSOLETE. Any constituent part of a chloroplast, a chlorophyll-containing plastid with thylakoids organized into grana and frets, or stroma thylakoids, and embedded in a stroma.

The chemical reactions and pathways resulting in the breakdown of L-alanine to D-lactate and ammonia.

OBSOLETE. Any constituent part of a plastid, a member of a family of organelles found in the cytoplasm of plants and some protists, which are membrane-bounded and contain DNA. Plant plastids develop from a common type, the proplastid.

OBSOLETE. Any constituent part of a membrane, a double layer of lipid molecules that encloses all cells, and, in eukaryotes, many organelles; may be a single or double lipid bilayer; also includes associated proteins.
