sodium-exporting ATPase activity, phosphorylative mechanism

sodium exporting ATPase activity, phosphorylative mechanism

Catalysis of the reaction: ATP + H2O + Na+(in) = ADP + phosphate + Na+(out), by a phosphorylative mechanism.

Any complex of pre-rRNAs, ribosomal proteins, and associated proteins formed in the nucleolus during ribosome biogenesis.

Progression through G2 phase, one of two 'gap' phases in the mitotic cell cycle; G2 is the interval between the completion of DNA synthesis and the beginning of mitosis.

The inhibition of the passage of calcium ions through a calcium channel; the function of some venoms.

Progression from G2 phase to M phase of the mitotic cell cycle.

The formation from simpler components of pyrimidine bases, 1,3-diazine, organic nitrogenous bases.

Progression through M phase, the part of the mitotic cell cycle during which mitosis and cytokinesis take place.

Interacting selectively with FAD, flavin-adenine dinucleotide, the coenzyme or the prosthetic group of various flavoprotein oxidoreductase enzymes.

Catalysis of the reaction: solute A(out) + solute B(in) = solute A(in) + solute B(out).

nucleolar preribosome, small subunit precursor

A preribosomal complex consisting of 20S pre-rRNA, ribosomal proteins including late-associating small subunit proteins, and associated proteins; a precursor of the eukaryotic cytoplasmic small ribosomal subunit.

reduced nicotinamide adenine dinucleotide phosphate binding

Interacting selectively with nicotinamide-adenine dinucleotide phosphate, a coenzyme involved in many redox and biosynthetic reactions; binding may be to either the oxidized form, NADP, or the reduced form, NADPH.

Catalysis of the reaction: anion A(out) + anion B(in) = anion A(in) + anion B(out).

Progression through metaphase, the stage of mitosis at which chromosomes are firmly attached to the mitotic spindle at its equator but have not yet segregated to opposite poles.

Catalysis of the reaction: ATP + H2O + xenobiotic(in) = ADP + phosphate + xenobiotic(out).
