Unwinding of a DNA/RNA duplex in the 5' to 3' direction, driven by ATP hydrolysis.

The process of regulating the proliferation and elimination of T cells such that the total number of T cells within a whole or part of an organism is stable over time in the absence of an outside stimulus.

The cross-linking of a tryptophan residue to tryptophyl quinone to form 4'-(L-tryptophan)-L-tryptophyl quinone, a cofactor found at the active site of methylamine dehydrogenase.

The modification of protein tyrosine to L-2',4',5'-topaquinone, characteristic of the active site of copper amine oxidases.

The modification of protein tyrosine to peptidyl-L-3',4'-dihydroxyphenylalanine (DOPA).

OBSOLETE. The covalent attachment of a cofactor to a protein.

Catalysis of the reaction: L-histidyl-[protein] + S-adenosyl-L-methionine = N(tele)-methyl-L-histidyl-[protein] + S-adenosyl-L-homocysteine.

OBSOLETE. The bromination of peptidyl-histidine to form peptidyl-L-bromohistidine; the position of the bromine substitution is unknown.

OBSOLETE. The addition of one or more bromine atoms to an amino acid residue in a protein.

The modification of peptidyl-glutamic acid residues by the covalent attachment of ethanolamine, itself further modified by the addition of a phosphoglycerol unit.

Catalysis of the reaction: NAD(P)+ + L-cysteine = nicotinamide + N2-(ADP-D-ribosyl)-L-cysteine.

The phosphopantetheinylation of peptidyl-serine to form peptidyl-O-phosphopantetheine-L-serine.

Binds to and stops, prevents or reduces the activity of a cysteine-type endopeptidase involved in the apoptotic process.

The portion of a neuron that includes the nucleus, but excludes cell projections such as axons and dendrites.

Binding to a small ribosomal subunit.

Binding to a large ribosomal subunit.

A enzyme complex of which the core is a heterodimer composed of a light (alpha) and heavy (beta) chain, and requires several other water-soluble proteins of cytosolic origin for activity. Functions in superoxide generation by the NADPH-dependent reduction of O2.

The assembly of neurofilaments into bundles, in which the filaments are longitudinally oriented, with numerous crossbridges between them. Neurofilament bundles may be cross-linked to each other, to membrane-bounded organelles or other cytoskeletal structures such as microtubules.

OBSOLETE. Any process that increases the extent of heterochromatin formation; increases the size of a chromosomal region converted to heterochromatin.
