| atrial granule serine proteinase | <enzyme> Converts pro-atrial natriuretic factor to anf by cleaving the arg98-ser99 bond; n-terminal 26-residue amino acid sequence given in first source Registry number: EC 3.4.21.- (26 Jun 1999) |
| azurophil granule | <cell biology> Primary lysosomal granules found in neutrophil granulocytes, contain a wide range of hydrolytic enzymes. Sometimes referred to as primary granules to distinguish them from the specific or secondary granules. (02 Jan 1998) |
| Babes-Ernst granule | <microbiology> Metachromatic intracellular deposits of polyphosphate found in Corynebacterium diphtheriae when the bacteria are grown on sub optimal media. The granules stain reddish with methylene blue or toluidine blue. (02 Jan 1998) |
| basal granule | <cell biology> Structure found at the base of eukaryotic cilia and flagella consisting of a continuation of the nine outer sets of axonemal microtubules but with the addition of a C tubule to form a triplet (like the centriole). May be self replicating and serves as a nucleating centre for axonemal assembly. Anchored in the cytoplasm by rootlets. Synonymous with kinetosome. (18 Nov 1997) |
| basophil granule | A granule that stains readily with a basic dye. (05 Mar 2000) |
| beta granule | A granule of a beta cell. (05 Mar 2000) |
| Birbeck's granule | A small tennis racket-shaped membrane-bound granule with characteristic cross-striated internal ultrastructure; first reported in Langerhans' cells of the epidermis. Synonym: Birbeck's granule. (05 Mar 2000) |
| Palade granule | <cell biology> A small particulate organelle found in prokaryotes and eukaryotes and also within mitochondria and chloroplasts, but differing in size and composition. Made of two subunits, each being an RNA protein complex. Ribosomes are responsible for the translation of mRNA which may occur in the cytoplasm (see polyribosomes) or on rough endoplasmic reticulum. Origin: Gr. Soma = body (18 Nov 1997) |
| volutin granule | Metachromatic granules containing polyphosphate, a linear phosphate polymer found in bacteria, fungi, algae and some higher eukaryotes that may serve as a stock of phosphate. (18 Nov 1997) |
| glycogen granule | Glycogen occurring in cells as beta granule's which average about 300 A |
| membrane-coating granule | A membrane-bound granule, 100 to 500 nm in diameter, located in the upper layers of the stratum spinosum of certain stratified squamous epithelia. Synonym: lamellar granule, membrane-coating granule, Odland body. (05 Mar 2000) |
| granule | <pharmacology> A small quantity of a solid substance, smaller than a grain. Origin: L. Granulum (18 Nov 1997) |
| granule cell | Type of neuron found in the cerebellum. (18 Nov 1997) |
| granule cell of connective tissue | <cell biology, immunology> Resident cell of connective tissue that contains many granules rich in histamine and heparan sulphate. Release of histamine from mast cells is responsible for the immediate reddening of the skin in a weal and flare response. Very similar to basophils and possibly derived from the same stem cells. Two types of mast cells are now recognised, those from connective tissue and a distinct set of mucosal mast cells, the activities of the latter are T-cell dependent. (05 Jan 1998) |
