| pyronin | A fluorescent red basic xanthene dye, the chloride of tetramethyldiaminoxanthene, pyronin Y or pyronin G, or of tetraethyldiaminoxanthene pyronin B. These dyes, especially pyronin Y, are used in combination with methyl green for differential staining of RNA (red) and DNA (green); difference in staining result is probably due to the higher degree of polymerization of DNA; pyronin Y is also used as a tracking dye for RNA in electrophoresis.

| pyronine | <chemical> [6-(dimethylamino0-3h-xanthen-3ylidine]dimethylammonium chloride. Xanthene dye used as a bacterial and biological stain. Synonym: pyronin; pyronine g; pyronine y. Use also for pyronine b. Which is diethyl-rather than dimethylamino-. Pharmacological action: dyes. Chemical name: Xanthylium, 3,6-bis(dimethylamino)-, chloride (12 Dec 1998) |
| pyroninophilia | An affinity for the basic pyronin dyes; a useful indicator of intense protein synthesis accompanying RNA synthesis, as in the cytoplasm of an active plasma cell. Origin: pyronin + G. Philos, fond (05 Mar 2000) |
| pyrope | <chemical> A variety of garnet, of a poppy or blood-red colour, frequently with a tinge of orange. It is used as a gem. See the Note under Garnet. Origin: L. Pyropus a kind of red bronze, fr. Gr.; fire + the eye, face: cf. F. Pyrope. Source: Websters Dictionary (01 Mar 1998) |
| pyrophane | <chemical> A mineral which is opaque in its natural state, but is said to change its colour and become transparent by heat. See: Pyrophanous. Source: Websters Dictionary (01 Mar 1998) |
| pyrophobia | <psychology> Morbid dread of fire. Origin: pyro-+ G. Phobos, fear (05 Mar 2000) |
| pyrophorous | Light-producing; of or pertaining to pyrophorus. <chemistry> Pyrophoric iron, finely reduced iron, which ignites spontaneously on contact with air. Origin: Pyro- + Gr. To bear. Source: Websters Dictionary (01 Mar 1998) |
| pyrophorus | <chemistry> Any one of several substances or mixtures which phosphoresce or ignite spontaneously on exposure to air, as a heated mixture of alum, potash, and charcoal, or a mixture of charcoal and finely divided lead. Origin: NL. See Pyrophorous. Source: Websters Dictionary (01 Mar 1998) |
| pyrophosphatase | Any enzyme cleaving a pyrophosphate bond between two phosphoric groups, leaving one on each of the two fragments; e.g., inorganic pyrophosphatase, NAD+ p. (cleaves NAD, etc., to mononucleotides), ATP pyrophosphatase (cleaves inorganic pyrophosphate from ATP, leaving AMP). See: flavin adenine dinucleotide. (05 Mar 2000) |
| pyrophosphatases | <enzyme> A group of enzymes within the class EC 3.6.1.- that catalyze the hydrolysis of diphosphate bonds, chiefly in nucleoside di- and triphosphates. They may liberate either a mono- or diphosphate. Registry number: EC 3.6.1.- (12 Dec 1998) |
| pyrophosphate | <chemistry> Two phosphate groups linked by esterification. Released in many of the synthetic steps involving nucleotide triphosphates (e.g. Protein and nucleic acid elongation). Rapid cleavage by enzymes that have high substrate affinity ensures that these reactions are essentially irreversible. (18 Nov 1997) |
| pyrophosphate translocase | <enzyme> A component of the glucose-6-phosphatase (g6pase, EC 3.1.3.9) enzyme complex; facilitates the transfer of pyrophosphate between the cell cytosol and the lumen of the endoplasmic reticulum where the g6pase enzyme is situated Registry number: EC 2.7.- (26 Jun 1999) |
| pyrophosphate-nucleoside kinase | <enzyme> From acholeplasma laidlawii; phosphorylates adenosine, inosine, and guanosine to the corresponding mononucleotides Registry number: EC 2.7.1.- Synonym: ppi dependent nucleoside kinase (26 Jun 1999) |
| pyrophosphate-protein phosphotransferase | <enzyme> Not dependent on ATP; inhibited by fluoride Registry number: EC 2.7.1.- (26 Jun 1999) |
| pyrophosphate-serine phosphotransferase | <enzyme> Catalyses the conversion of pyrophosphate and serine to form phosphoserine and orthophosphate Registry number: EC 2.7.1.80 (26 Jun 1999) |
