| Gomori's non-specific alkaline phosphatase stain | <technique> A calcium-cobalt sulfide method using frozen sections or cold acetone-or formalin-fixed paraffin sections, plus sodium beta-glycerophosphate as a substrate at pH 9.0 to 9.5 with Mg++ as activator; calcium ions precipitate the liberated phosphate, cobalt salt replaces the calcium phosphate, and ammonium sulfide converts the product to a black cobalt sulfide.

| group-specific protease | <enzyme> A serine protease, obtained from rat small intestine, which preferentially inactivates the apo forms of certain pyridoxal phosphate requiring enzymes Registry number: EC 3.4.21.- (26 Jun 1999) |
| RNA, transfer, amino acid-specific | A group of transfer rnas which are specific for carrying each one of the 20 amino acids to the ribosome in preparation for protein synthesis. (12 Dec 1998) |
| poly A specific exoribonuclease | <enzyme> Acts on 2' or 3'-linked oligoriboadenylates to liberate 5'-AMP Registry number: EC 3.1.13.- Synonym: 2',3'-exoribonuclease, 3'-exoribonuclease (26 Jun 1999) |
| poly(A)-specific ribonuclease | <enzyme> From vigna unguiculata seedlings; bifunctional enzyme responsible for both poly(a)-polymerizing and poly(a)-hydrolyzing activities; removes the poly(a) tail as the first step in degrading mRNA Registry number: EC 3.1.13.4 Synonym: poly(a) nuclease, mRNA poly(a) nuclease, poly(a) ribonuclease (pan), pan2 protein (26 Jun 1999) |
| myelencephalon-specific serine protease | <enzyme> Specifically expressed in the nervous system; plays a role in normal homeostasis and response of spinal cord to injury. Registry number: EC 3.4.21.- Synonym: myelencephalon-specific protease, msp enzyme (26 Jun 1999) |
| pregnancy-specific beta 1-glycoprotein | A glycoprotein with the electrophoretic mobility of a beta-1 globulin. It is produced by the placental trophoblast and secreted into the maternal bloodstream during pregnancy. It can be detected 18 days after ovulation and its concentration in plasma rises steadily until, at the end of gestation, it reaches 200 mg/ml. It has been proposed as a measure of placental function for fertility control and is a candidate for an early pregnancy test. (12 Dec 1998) |
| prenylated peptide-specific endoprotease | <enzyme> Cleaves c-terminal tripeptide from prenylated protein having c-terminal sequence caax; race is rac and a-factor converting enzyme with same activity Registry number: EC 3.4.14.- Synonym: prenylated protein endoprotease, race enzyme, isoprenylated protein endopeptidase, isoprenylated protein endoprotease (26 Jun 1999) |
| cytosol non-specific dipeptidase | <enzyme> Also referred to as peptidase a (see synonym to penicillopepsin, EC 3.4.23.20) Registry number: EC 3.4.13.- Synonym: glycyl-l-leucine hydrolase, glycylleucine dipeptidase, gly-leu dipeptide peptidase, dipeptide hydrolase, glycyl-leucine dipeptidase (26 Jun 1999) |

| site-specific mutagenesis | <cell culture, molecular biology> An in vitro technique in which an alteration is made at a specific site in a DNA molecule, which is then reintroduced into a cell. Various techniques are used, for the cell biologist, a very powerful approach to determining which parts of a protein or nucleotide sequence are critical to function. (18 Nov 1997) |
| site specific mutation | An alteration of the structure of a gene at a specific sequence, usually referring to experimentally produced changes in gene sequence. (05 Mar 2000) |
| site-specific recombination | <molecular biology> A type of recombination that occurs between two specific short DNA sequences present in the same or in different molecules. An example is the integration and excision of _ prophage. (18 Nov 1997) |
