Interacting selectively with cations, charged atoms or groups of atoms with a net positive charge.

The molecular events that lead to the integration of a viral genome into the host genome.

negative regulation of caspase activation

Any process that stops, prevents or reduces the rate of caspase activation.

The lipid bilayer and associated glycoproteins that surround many types of virus particle.

The chemical reactions involving polyisoprenoids, acyclic polymers containing a large number of isoprene subunits, usually unsaturated.

Catalysis of the reaction: NADPH + H+ + quinone = NADP+ + semiquinone.

Targeting of a vesicle to a specific destination membrane.

Catalysis of the reaction: ATP + RNA 3'-terminal-phosphate = AMP + diphosphate + RNA terminal-2',3'-cyclic-phosphate.

The initial attachment of a vesicle membrane to a target membrane, mediated by proteins protruding from the membrane of the vesicle and the target membrane, during exocytosis.

Catalysis of the reaction: deoxynucleoside triphosphate + DNA(n) = diphosphate + DNA(n+1). Catalyzes RNA-template-directed extension of the 3'- end of a DNA strand by one deoxynucleotide at a time.

The process whereby phagocytes engulf external particulate material. The particles are initially contained within phagocytic vacuoles (phagosomes), which then fuse with primary lysosomes to effect digestion of the particles.

A structure composed of a very long molecule of DNA and associated proteins (e.g. histones) that carries hereditary information.

The chemical reactions involving macromolecules, large molecules including proteins, nucleic acids and carbohydrates.

Catalysis of the reaction: NAD+ + (ADP-D-ribosyl)(n)-acceptor = nicotinamide + (ADP-D-ribosyl)(n+1)-acceptor.

Catalysis of the reaction: ATP + NAD+ = ADP + NADP+.

Catalysis of the reaction: NAD+ + H2O = nicotinamide + ADP-ribose.

Any process which produces a nucleotide, a nucleobase linked to either beta-D-ribofuranose (ribonucleoside) or 2-deoxy-beta-D-ribofuranose, (a deoxyribonucleotide),from derivatives of it without de novo synthesis.
