| vectorial capacity | <epidemiology> In vector-borne infections such as malaria, the vectorial capacity is a concept analogous to the contact rate in directly-transmitted diseases. It is, thus, a function of (a) the vector's density in relation to its vertebrate host, (b) the frequency with which it takes blood meals on the host species, (c) the duration of the latent period in the vector, and (d) the vector's life expectancy.

| vectorial synthesis | <cell biology> Term usually applied to the mode of synthesis of proteins destined for export from the cell. As the protein is made it moves (vectorially) through the membrane of the rough endoplasmic reticulum, to which the ribosome is attached and into the cisternal space. (06 Mar 2000) |
| vectorial transport | <physiology> Transport of an ion or molecule across an epithelium in a certain direction (e.g. absorption of glucose by the gut). Vectorial transport implies a nonuniform distribution of transport proteins on the plasma membranes of two faces of the epithelium. (06 Mar 2000) |
| phosphorylation | <biochemistry> The creation of a phosphate derivative of an organic molecule. This isusually achieved by transferring a phosphate group from ATP. (09 Oct 1997) |
| phosphorylation of proteins | <biochemistry> Addition of phosphate groups to hydroxyl groups on proteins (side chains s, T or Y) catalysed by a protein kinase often specific) with ATP as phosphate donor. Activity of proteins is often regulated by phosphorylation. (18 Nov 1997) |
| cyclic phosphorylation | Any process in which a phosphatide ester forms a cylic diester by linkage to a neighbouring hydroxyl group. (18 Nov 1997) |
| substrate-level phosphorylation | Synthesis of high-energy phosphate bonds through reaction of inorganic phosphate with an activated (usually) organic substrate. (09 Oct 1997) |
| oxidative phosphorylation | <biochemistry> The phosphorylation of ATP coupled to the respiratory chain. (18 Nov 1997) |
| electron transport phosphorylation | <biochemistry> Synthesis of ATP involving a membrane associated electron transport chain and the creation of a proton-motive force. (09 Oct 1997) |
| tyrosine phosphorylation | <enzyme> Kinases that phosphorylate protein tyrosine residues. These kinases play major roles in mitogenic signalling and can be divided into two subfamilies: receptor tyrosine kinases, that have an extracellular ligand binding domain, a single transmembrane domain and an intracellular tyrosine kinase domain and nonreceptor tyrosine kinases, which are soluble, cytoplasmic kinases.
