The double lipid bilayer enclosing the nucleus and separating its contents from the rest of the cytoplasm; includes the intermembrane space, a gap of width 20-40 nm (also called the perinuclear space).

A multienzyme complex that catalyzes the formation N-carbamoyl-L-aspartate from carbamoyl phosphate and L-aspartate. It exhibits a variety of architectural organizations, but in all microorganisms the core catalytic component is a homotrimer of approximately 34 kDa polypeptides.

Catalysis of the reaction: 3'-phosphoadenosine 5'-phosphosulfate + taurolithocholate = adenosine 3',5'-bisphosphate + taurolithocholate sulfate.

An enzyme complex that catalyzes the transfer of a carbamoyl to ornithine, forming citrulline.

The inner, i.e. lumen-facing, lipid bilayer of the nuclear envelope.

oxidoreductase activity, acting on other nitrogenous compounds as donors

oxidoreductase activity, acting on other nitrogenous compounds as donors, other acceptors

Catalysis of an oxidation-reduction (redox) reaction in which a nitrogenous group, excluding NH and NH2 groups, acts as a hydrogen or electron donor and reduces a hydrogen or electron acceptor.

Any of a group of intermediate-filament proteins that form the fibrous matrix on the inner surface of the nuclear envelope. They are classified as lamins A, B and C.

Penetrating at least one phospholipid bilayer of the nuclear inner membrane. May also refer to the state of being buried in the bilayer with no exposure outside the bilayer.

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

oxidoreductase activity, acting on other nitrogenous compounds as donors, oxygen as acceptor

Catalysis of an oxidation-reduction (redox) reaction in which a nitrogenous group, excluding NH and NH2 groups, acts as a hydrogen or electron donor and reduces oxygen.

oxidoreductase activity, acting on sulfur group of donors

oxidoreductase activity, acting on sulfur group of donors, other acceptors

Catalysis of an oxidation-reduction (redox) reaction in which a sulfur-containing group acts as a hydrogen or electron donor and reduces a hydrogen or electron acceptor.
