protection
| browse protection | <ecology> Mechanical or chemical protection of shrubs and trees against damage caused by game and grasing animals. (09 Oct 1997) |
|---|---|
| cathodic protection | <chemistry> The attachment of an active metal to a system to protect the system from corrosion. The active metal serves as the anode, making the metal in the system a cathode. (16 Mar 1998) |
| protection | Synonym: protective block. Origin: see protective (05 Mar 2000) |
| protection test | A test to determine the antimicrobial activity of a serum by inoculating a susceptible animal with a mixture of the serum and the virus or other microbe being tested. Synonym: neutralization test. (05 Mar 2000) |
| sun protection factor | A number on a scale (from 2 upwards) for rating sunscreens. Sunscreens with an spt of 15 or higher provide the best protection from the sun's harmful rays. (12 Dec 1998) |
| ecological protection | <ecology> Protection consists of measures undertaken to protect and preserve elements of an ecosystem's structure and functions against future degradation. (10 Nov 1998) |
| environmental protection agency | <organisation> The U.S. Regulatory agency for biotechnology of microbes. The major lawsunder which the agency has regulatory powers are the Federal Insecticide, Fungicide, and Rodenticide act (FIFRA), and the Toxic Substances ControlAct (TSCA). (30 Mar 1998) |
| united states environmental protection agency | An agency in the executive branch which endeavors to abate and control pollution in the areas of air, water, solid waste, noise, radiation, and toxic substances. (12 Dec 1998) |
| Bacillus pumilus ribonuclease | <enzyme> The extracellular ribonuclease of b. Pumilus kmm62; shares 98% structural identity with binase, 72% with barnase; genbank u06867 Registry number: EC 3.1.4.- Synonym: bacillus pumilus rnase, rnase bp (26 Jun 1999) |
| Pac1 ribonuclease | <enzyme> A homolog of e. Coli rnase III from schizosaccharomyces pombe; amino acid sequence given in first source Registry number: EC 3.1.26.- Synonym: rnase pac1, pac1 gene product (26 Jun 1999) |
| ribonuclease | <biochemistry, enzyme, molecular biology> Widely distributed type of enzyme that cleaves RNA. May act as endonucleases or exonucleases depending upon the type of enzyme. Generally recognise target by tertiary structure rather than sequence. Ribonuclease E is involved in the formation of 5S ribosomal RNA from pre rRNA. Ribonuclease F is stimulated by interferons and cleaves viral and host RNA and thus inhibits protein synthesis. Ribonuclease H specifically cleaves an RNA base paired to a complementary DNA strand. Ribonuclease P is an endonuclease that generate t RNA from their precursor transcripts. Ribonuclease T is an endonuclease that removes the terminal AMP from the 3' CCA end of a nonaminoacylated tRNA. Ribonuclease T1 cleaves RNA specifically at guanosine residues. Ribonuclease TIII cleaves double stranded regions of RNA molecules. Acronym: RNase (23 Aug 1998) |
| ribonuclease (Bacillus subtilis) | 1. Ribonuclease (Azotobacter agilis); ribonuclease (Proteus mirabilis); an enzyme catalyzing the endonucleolytic cleavage of RNA to yield 2',3'-cyclic nucleotides. 2. Ribonuclease T1. (05 Mar 2000) |
| ribonuclease D | <enzyme> An enzyme (endonuclease) that trims the extra 3' nucleotides from immature tRNA. (05 Mar 2000) |
| ribonuclease h, calf thymus | <enzyme> A ribonuclease that specifically cleaves the RNA moiety of RNA:DNA hybrids. It has been isolated from a wide variety of prokaryotic and eukaryotic organisms (particularly calf thymus) as well as retroviruses. Registry number: EC 3.1.26.4 (12 Dec 1998) |
| ribonuclease (pancreatic) |
