Processes by which a myeloid precursor cell acquires specializes features of an erythrocyte without a nucleus, as found in mammals.

Catalysis of the reaction: 5-alpha-cholest-7-en-3-beta-ol + O2 = cholesta-5,7-dien-3-beta-ol + H2O2.

Catalysis of the reaction: biotin amide + H2O = biotin + NH3.

Catalysis of the reaction: L-pipecolate + O2 = 2,3,4,5-tetrahydropyridine-2-carboxylate + H2O2.

Catalysis of the reaction: xylitol + NADP+ = L-xylulose + NADPH.

The chemical reactions involving S-adenosylhomocysteine; the L-enantiomer is formed from S-adenosylmethionine and is a strong inhibitor of S-adenosylmethionine-mediated methylation reactions. It can be cleaved to form adenosine and homocysteine.

The process of elimination of immature T cells in the thymus which react strongly with self-antigens.

Processes of T cell selection that occur in the thymus.

The directed movement of metal ions, any metal ion with an electric charge, into, out of, within or between cells.

Processes of T cell selection that occur in extrathymic locations, often resulting T cells of distinct specificities from those selected in the thymus.

The regulation of the levels, transport, and metabolism of anions within a cell or between a cell and its external environment.

The process whereby a relatively unspecialized T cell acquires the specialized features of a Th1 cell.

The regulation of the levels, transport, and metabolism of cations within a cell or between a cell and its external environment.

The regulation of the levels, transport, and metabolism of monovalent inorganic cations within a cell or between a cell and its external environment.

The process whereby a relatively unspecialized T cell acquires specialized features of a cytotoxic T cell.

The posttranslational phosphorylation of peptidyl-serine to form peptidyl-O-phospho-L-serine.

di-, tri-valent inorganic cation homeostasis

The regulation of the levels, transport, and metabolism of divalent and trivalent inorganic cations within a cell or between a cell and its external environment.
