polymeric immunoglobulin binding

Binding to a J-chain-containing polymeric immunoglobulin of the IgA or IgM isotypes.

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).

2-oxopropyl-CoM reductase (carboxylating) activity

Catalysis of the reaction: acetoacetate + coenzyme M + NADP+ = 2-oxopropyl-coenzyme M + CO2 + NADPH.

DNA ligase (ATP) activity

Catalysis of the reaction: ATP + deoxyribonucleotide(n) + deoxyribonucleotide(m) = AMP + diphosphate + deoxyribonucleotide(n+m).

DNA ligase (NAD+) activity

Catalysis of the reaction: NAD+ + deoxyribonucleotide(n) + deoxyribonucleotide(m) = AMP + nicotinamide nucleotide + deoxyribonucleotide(n+m).

somatic diversification of T cell receptor genes by N region addition

The addition of variable numbers of random nucleotides by terminal deoxytransferase in the N regions of T cell receptor genes. N regions are found at the V-D, D-D, V-J, and D-J recombinational junctions, depending on the T cell receptor gene.

obsolete thiol-driven fumarate reductase activity

OBSOLETE. Catalysis of the reaction: fumarate + coenzyme M + coenzyme B = succinate + coenzyme M + coenzyme B + heterodisulfide.

2-(R)-hydroxypropyl-CoM dehydrogenase activity

Catalysis of the reaction: 2-(R)-hydroxypropyl-coenzyme M + NAD+ = 2-oxopropyl-coenzyme M + H+ + NADH.

2-(S)-hydroxypropyl-CoM dehydrogenase activity

Catalysis of the reaction: 2-(S)-hydroxypropyl-coenzyme M + NAD+ = 2-oxopropyl-coenzyme M + H+ + NADH.
