| minimum protein requirement | <nutrition> The age-dependent amount of protein required daily in the diet. (05 Mar 2000) |
|---|---|
| coat protein | <protein> The proteins which make up the outer coat of a virus (called the capsid). (09 Oct 1997) |
| molybdenum-iron protein aldehyde oxidoreductase | <enzyme> Related to xanthine oxidase; isolated from desulfovibrio gigas Registry number: EC 1.2.7.- Synonym: mop protein (26 Jun 1999) |
| monoclonal protein | A homogenous immunoglobulin resulting from the proliferation of a single clone of plasma cells and which, during electrophoresis of serum, appears as a narrow band or "spike"; it is characterised by heavy chains of a single class and subclass, and light chains of a single type. Synonym: M protein, monoclonal protein, paraprotein. (05 Mar 2000) |
| monocyte chemoattractant protein-1 | <cytokine> A chemokine that is a chemoattractant for human monocytes and may also cause cellular activation of specific functions related to host defense. It is produced by leukocytes of both monocyte and lymphocyte lineage and by fibroblasts during tissue injury. Synonym: monocyte chemotactic and activating factor (12 Dec 1998) |
| pi protein | <protein> Polypeptide (35 kD) that is required for the initiation of DNA replication in the R6K antibiotic resistance plasmid, of which there are 12-18 copy equivalents in the E. Coli chromosome. (18 Nov 1997) |
| PK40(erk) protein kinase | <enzyme> A member of the erk family of serine/threonine-proline kinases; hyperphosphorylates tau protein in neurofibrillary tangles of alzheimer's disease subsequent to phosphorylation by camp-dependent protein kinase a; has been sequenced Registry number: EC 2.7.1.- Synonym: pk40(erk2), erk2 brain kinase pk40 (26 Jun 1999) |
| PKN protein kinase | <enzyme> Catalytic domain homologous to protein kinase c; genbank d26181 (human) and genbank d26180 (rat); do not confuse with protein kinase n Registry number: EC 2.7.1.- (26 Jun 1999) |
| placental calcium-binding protein | <protein> Calcium binding protein of placenta, uterus and vasculature containing the EF hand motif. (18 Nov 1997) |
| placenta protein | human placental lactogen |
| whey protein | The soluble protein contained in the whey of milk clotted by rennin; e.g., lactoglobulin, alpha-lactalbumin, lactoferrin. (05 Mar 2000) |
| 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. (18 Nov 1997) |
| 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. (14 Oct 1997) |
| MST1 protein kinase | <enzyme> Mst1 - mammalian sterile twenty-like; homologous to ste20; genbank u18297; do not confuse with the monosaccharide transporter mst1 protein Registry number: EC 2.7.10.- (26 Jun 1999) |
