- phytochromobilin biosynthetic process
The chemical reactions and pathways resulting in the formation of phytochromobilin, which involves the oxidative cleavage of heme by a heme oxygenase(HO) to form biliverdin IX alpha.
- phycocyanobilin biosynthetic process
The chemical reactions or pathway resulting in the formation of phycocyanobilin, which involves the oxidative cleavage of heme by a heme oxygenase (HO) to form biliverdin IX alpha. Biliverdin IX alpha is subsequently converted to phycocyanobilin by a ferredoxin-dependent oxidoreductase (PCYA).
- V(D)J recombination
The process in which immune receptor V, D, and J, or V and J gene segments, depending on the specific receptor, are recombined within a single locus utilizing the conserved heptamer and nonomer recombination signal sequences (RSS).
- T cell receptor V(D)J recombination
The process in which T cell receptor V, D, and J, or V and J gene segments, depending on the specific locus, are recombined within a single locus utilizing the conserved heptamer and nonomer recombination signal sequences (RSS).
- somatic diversification of immune receptors by N region addition
The addition of variable numbers of random nucleotides by terminal deoxytransferase in the N regions of heavy chain immunoglobulin and T cell receptor genes. N regions are found at the V-D, D-D, V-J, and D-J recombinational junctions, depending on the immune receptor gene.
- immunoglobulin V(D)J recombination
The process in which immunoglobulin gene segments are recombined within a single locus utilizing the conserved heptamer and nonomer recombination signal sequences (RSS). For immunoglobulin heavy chains V, D, and J gene segments are joined, and for immunoglobulin light chains V and J gene segments are joined.
