ribophage |
A bacteriophage that hasan RNA-based genetic structure. (09 Oct 1997) |
|---|---|
ribophorin |
<protein> Glycoproteins of the endoplasmic reticulum that interact with ribosomes whilst co translational insertion of membrane or secreted proteins is taking place. Ribophorins may form a pore through which the nascent polypetide chain passes. (18 Nov 1997) |
ribophorins |
Ribosome receptor proteins that interact specifically with the large ribosomal subunit and aid in translocation of newly synthesised proteins across the endoplasmic reticulum. Origin: ribonucleic acid + G. Phoros, carrying, + -in (05 Mar 2000) |
riboprine |
<drug> An anti-cancer drug. (09 Oct 1997) |
riboprobe |
Somewhat casual term for an RNA segment used to probe for a complementary nucleotide sequence either in the mRNA pool or in the DNA of a cell. (18 Nov 1997) |
ribopyranose |
The 1,5-cyclic form of ribose. (05 Mar 2000) |
ribose |
A monosaccharide pentose of widespread occurrence in biological molecules, for example RNA. (18 Nov 1997) |
ribose binding protein |
<protein> Periplasmic binding proteins of bacteria that interact either with the ribose transport system or with the methyl accepting chemotaxis protein MCP III (trg). (18 Nov 1997) |
ribose polymerase |
<enzyme> Enzyme that catalyses the attachment of ADP ribose units to various nuclear proteins. This post translational modification of proteins is dependent on DNA and appears to be involved in the regulation of various cellular processes such as differentiation, proliferation and transformation. (18 Nov 1997) |
ribose-1,5-diphosphate synthase |
<enzyme> Uses ribose 1-(or 5)p as phosphoryl acceptor and acyl-p of 3-phosphoglyceroylphosphate as phosphoryl donor; similar reaction to glucose 1,6-bisphosphate synthase Registry number: EC 2.7.1.- Synonym: ribose-1,5-p2 synthase (26 Jun 1999) |
ribose-5-phosphate |
Ribose phosphorylated on carbon-5; an intermediate in the pentose phosphate pathway. (05 Mar 2000) |
ribose-5-phosphate isomerase |
<enzyme> An enzyme catalyzing interconversion of d-ribose 5-phosphate and d-ribulose 5-phosphate; of importance in ribose metabolism and in the pentose phosphate pathway. Synonym: phosphopentose isomerase, phosphoriboisomerase. (05 Mar 2000) |
ribose-phosphate pyrophosphokinase |
<enzyme> An enzyme that catalyses the formation of phosphoribosyl pyrophosphate from ATP and ribose-5-phosphate. Chemical name: ATP:ribose-5-phosphate pyrophosphotransferase Registry number: EC 2.7.6.1 (12 Dec 1998) |
ribosemonophosphates |
Ribose substituted in the 1-, 3-, or 5-position by a phosphoric acid moiety. (12 Dec 1998) |
riboside |
<biochemistry> A glycoside that has ribose as its sugar component. (09 Oct 1997) |
