| motor protein | <protein> Proteins that bind ATP and are able to move on a suitable substrate with concomitant ATP hydrolysis. most eukaryotic motor proteins move by binding to a specific site on either actin filaments (myosin) or on microtubules (dynein, kinesin). They are normally elongated molecules with two active binding sites although some kinesin analogues have a single site. The distal end of the molecule normally binds adaptor proteins that enable them to make stable interactions with membranous vesicles or with filamentous structures, which then constitute the cargo to be moved along the substrate filament.

| M protein | 1. Galactoside carrier in E. Coli 2. Cell surface antigen of Brucella. 3. Structural protein in the M line of striated muscle (myomesin). (4) Cell wall protein of streptococci: antibody typing of the M protein is important in identification of different strains of Group A streptococci (at least 55 serotypes are known). The M protein confers antiphagocytic properties on the cell and is present as hair like fimbriae on the surface. M protein is an important virulence factor and antibodies directed against M protein are essential for phagocytic killing of the bacteria. (18 Nov 1997) |
| plasma protein | <haematology> One of the hundreds of different proteins present in blood plasma, including carrier proteins (such albumin, transferrin and haptoglobin), fibrinogen and other coagulation factors, complement components, immunoglobulins, enzyme inhibitors, precursors of substances such as angiotension and bradykinin and many other types of proteins.

| congenital protein C or s deficiency | This inherited disorder of blood coagulation is characterised by a deficiency of vitamin K dependent plasma proteins (C and s) that are naturally occurring anticoagulants. This disorder results in an increased risk of blood clot formation within the circulatory system. (27 Sep 1997) |
