The process of apoptosis in cells infected with a virus.

The chemical reactions involving tetrahydrobiopterin, the reduced form of biopterin (2-amino-4-hydroxy-6-(1,2-dihydroxypropyl)-pteridine). It functions as a hydroxylation coenzyme, e.g. in the conversion of phenylalanine to tyrosine.

programmed cell death, transformed cells

The process of apoptosis in transformed cells, cells that have undergone changes manifested by escape from control mechanisms, increased growth potential, alterations in the cell surface, karyotypic abnormalities, morphological and biochemical deviations from the norm.

Any process involved in the controlled movement of a cell.

The formation from simpler components of a pigment, any general or particular coloring matter in living organisms, e.g. melanin.

The orderly movement of cells from one site to another along a substrate such as the extracellular matrix; the migrating cell forms a protrusion that attaches to the substrate.

The breakdown into simpler components of a pigment, any general or particular coloring matter in living organisms, e.g. melanin.

Interacting selectively with galactose (galacto-hexose), a common constituent of many oligo- and polysaccharides.

Interacting selectively with mannose, a monosaccharide hexose, stereoisomeric with glucose, that occurs naturally only in polymerized forms called mannans.

ATP-binding cassette (ABC) transporter complex

A complex for the transport of metabolites into and out of the cell, typically comprised of four domains; two membrane-associated domains and two ATP-binding domains at the intracellular face of the membrane, that form a central pore through the plasma membrane. Each of the four core domains may be encoded as a separate polypeptide or the domains can be fused in any one of a number of ways into multidomain polypeptides. In bacteria and archaebacteria, ABC transporters also recruit substrate binding proteins to bind substrate external to the cell and deliver it to the transporter.

The transfer of virions in order to create new infection.
