| PP | <abbreviation> Pyrophosphate. (05 Mar 2000) |
|---|---|
| pp46 | <protein> Protein associated with actively growing axons, especially in the growth cone. Binds calmodulin, is phosphorylated by protein kinase C. (18 Nov 1997) |
| PP5 protein-serine-threonine phosphatase | <enzyme> Has 4 tetratricopeptide repeat (tpr) motifs; similar to ppt1 protein; do not confuse with the placental protein pp5; amino acid sequence given in first source Registry number: EC 3.1.3.- Synonym: pp5 phosphatase, protein phosphatase 5 (26 Jun 1999) |
| pp60 | <molecular biology> The phosphoprotein (60 kD) encoded by the src oncogene. A tyrosine kinase. (18 Nov 1997) |
| pp65 protein | <protein> A protein made by a cytomegalovirus which prevents the cell that the virus has infected from displaying fragments of viral proteins, called antigens, on the cells surface. In this way the cytomegalovirus is able to evade the bodys immune system, more or less permanently. (09 Oct 1997) |
| ppb | <abbreviation> Parts per billion. (05 Mar 2000) |
| PPCA | <abbreviation> Proserum prothrombin conversion accelerator. (05 Mar 2000) |
| PPCF | <abbreviation> Plasmin prothrombins conversion factor. (05 Mar 2000) |
| PPD | <abbreviation> Purified protein derivative of tuberculin. (05 Mar 2000) |
| ppd test | <dermatology, investigation> A simple skin test used to detect prior exposure to tuberculosis. PPD is injected under the skin of the forearm. After 48 to 72 hours, the injection site will exhibit a red, hard bump if a person has been infected with tuberculosis. (09 Oct 1997) |
| PPi | <abbreviation> Inorganic pyrophosphate. (05 Mar 2000) |
| PPIase | <enzyme> That accelerate protein folding by catalysing cis trans isomerisations. Immunophilins are PPIases though their enzymic activity may not be essential for their immunosuppressive effects. (18 Nov 1997) |
| PPLO | <abbreviation> Pleuropneumonia-like organisms. (05 Mar 2000) |
| ppm | <abbreviation> Parts per million. (05 Mar 2000) |
| PPM-1 beta-lactamase | <enzyme> From a cefuroxime-resistant strain of proteus mirabilis Registry number: EC 3.5.2.- Synonym: beta-lactamase fpm-1, fujisawa proteus mirabilis oxyiminocephalosporinase (26 Jun 1999) |
