| proteinaceous infectious particle | A proposed pathogen composedonly of protein with no detectable nucleic acid and which is responsible for Creutzfeldt-Jakob disease and kuru inhumans and scrapie in sheep. (09 Oct 1997) |

| high energy particle generating unit | A machine capable of providing highly energised radiation for the purposes of radiotherapy treatment. (16 Dec 1997) |
| signal recognition particle | A complex between a 7S RNA and six proteins. SRP binds to the nascent polypeptide chain of eukaryotic proteins with a signal sequence and halts further translation until the ribosome becomes associated with the rough endoplasmic reticulum. One of the SRP proteins (srp54) binds GTP and in association with 7SRNA and srp19 has GTPase activity. (18 Nov 1997) |
| signal recognition particle receptor | Receptor for the signal recognition particle (SRP) found in the membrane of the endoplasmic reticulum. Also called docking protein. Heterodimeric, both protomers having GTP binding capacity, though dissimilar binding sites. Not until the complex of SRP, ribosome, message and nascent polypeptide chain binds to the SRP receptor is the block to further chain elongation released and concurrently the SRP is released, leaving the ribosome attached to the endoplasmic reticulum membrane. Cotranslational transport of the polypeptide delivers it into the lumen of the ER. (18 Nov 1997) |
| submitochondrial particle | Formed by sonicating mitochondria. Small vesicles in which the inner mitochondrial membrane is inverted to expose the innermost surface. (18 Nov 1997) |
| dane particle | <virology> 42 nm spherical particle, the complete infective virion of hepatitis B containing a 27 nm core antigen. (27 Sep 1997) |
| defective interfering particle | An incomplete virus that is unable to replicate and interferes with replication of an infectious virus. (05 Mar 2000) |
| D.I. particle | <abbreviation> Defective interfering particle. (05 Mar 2000) |
| dressed particle | <radiobiology> A particle plus its associated neutralising Debye sphere. (09 Oct 1997) |
| intramembranous particle | <cell biology> Particles (or complementary pits) seen in freeze fractured membranes. The cleavage plane is through the centre of the bilayer and the particles are usually assumed to represent Integral membrane proteins (or polymers of such proteins). (18 Nov 1997) |
| either particle flux density | The particle fluence rate, or energy flux density, the energy fluence rate of intensity. Compare: fluence. (05 Mar 2000) |
| trapped-particle instability | <radiobiology> Slowly-growing class of instabilities driven by particles which cannot circulate freely in a toroidal system. See: banana orbit. (09 Oct 1997) |
| kappa particle | <microbiology> Gram-negative bacterial endosymbiont of Paramoecium spp., (Caedobacter taeniospiralis) that confers the killer trait, infected Paramoecium are resistant to the toxin liberated by infected forms. Killing activity is associated with the induction of defective phage in the endosymbiont, leading to the release of R bodies, coded for by the phage genome and apparently of mis assembled phage coat protein.
