| microtubule-associated protein 1B kinase | <enzyme> Serine-threonine-specific protein kinase which acts on microtubule-associated protein 1b (map1b); activated by various mitogens; does not act on map2 Registry number: EC 2.7.10.- Synonym: map1b kinase (26 Jun 1999) |
| microtubule-associated protein-2 phosphatase | <enzyme> does not fit into any of the classes of protein phosphatases (types 1,2a,2b and 2c) involved in cellular regulation Registry number: EC 3.1.3.- Synonym: map-2 phosphatase (26 Jun 1999) |
| cis-acting protein | A protein that acts on the molecule of DNA from which it was expressed. (05 Mar 2000) |
| phosphoenolpyruvate-protein phosphotransferase | <enzyme> Enzyme I of the system Registry number: EC 2.7.3.9 Synonym: enzyme I, phosphoenolpyruvate sugar phosphotransferase system, enzyme I peppts, ptsi gene product, ptsj gene product, ptsp gene product, enzyme i(ntr) (26 Jun 1999) |
| mild silver protein | A complex prepared by the reaction of silver oxide with either gelatin or serum albumin. Black shiny crystals liberate silver and it was formerly widely used as a topical anti-infective on mucous membranes. Contains from 19 to 25% silver, only a small fraction of which is ionizable. Can produce black or brown pigmentation due to deposition of reduced silver in the tissues. Synonym: argyrol, silvol. (05 Mar 2000) |
| phospholipid transfer protein | <protein> Cytoplasmic proteins that bind phospholipids and facilitate their transfer between cellular membranes. May also cause net transfer from the site of synthesis. (18 Nov 1997) |
| 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) |
