Porcupines - 새창
Common name for large, quilled rodents (RODENTIA) comprised of two families: Old World porcupines (Hystricidae) and New World porcupines (Erethizontidae).
Synonyms : Porcupine
Pore Forming Cytotoxic Proteins - 새창
Proteins secreted from an organism which form membrane-spanning pores in target cells to destroy them. This is in contrast to PORINS and MEMBRANE TRANSPORT PROTEINS that function within the synthesizing organism and COMPLEMENT immune proteins. These pore forming cytotoxic proteins are a form of primitive cellular defense which are also found in human LYMPHOCYTES.
Synonyms :
Porfiromycin - 새창
Toxic antibiotic of the mitomycin group, obtained from MITOMYCIN and also from Streptomyces ardus and other species. It is proposed as an antineoplastic agent, with some antibiotic properties.
Synonyms :
Porifera - 새창
The phylum of sponges which are sessile, suspension-feeding, multicellular animals that utilize flagellated cells called choanocytes to circulate water. Most are hermaphroditic. They are probably an early evolutionary side branch that gave rise to no other group of animals. Except for about 150 freshwater species, sponges are marine animals. They are a source of ALKALOIDS; STEROLS; and other complex molecules useful in medicine and biological research.
Synonyms : Sponge (Zoology), Sponges
Porins - 새창
Porins are protein molecules that were originally found in the outer membrane of GRAM-NEGATIVE BACTERIA and that form multi-meric channels for the passive DIFFUSION of WATER; IONS; or other small molecules. Porins are present in bacterial CELL WALLS, as well as in plant, fungal, mammalian and other vertebrate CELL MEMBRANES and MITOCHONDRIAL MEMBRANES.
