| secretory protein | <protein> In eukaryotes, proteins synthesised on rough endoplasmic reticulum and destined for export. Nearly all proteins secreted from cells are glycosylated (in the Golgi apparatus, although there are exceptions (albumin). In prokaryotes, secreted proteins may be synthesised on ribosomes associated with the plasma membrane or exported post translation. (18 Nov 1997) |

| purified placental protein | human placental lactogen |
| purified protein derivative of tuberculin | Purified tuberculin containing the active protein fraction; the tuberculin from which it is prepared differs from tuberculin chiefly in that the bacteria are grown in a synthetic rather than in a broth medium. (05 Mar 2000) |
| housekeeping protein | <molecular biology> Those sets of proteins involved in the basic functioning of a cell or the set of cells in an organism, for example enzymes involved in synthesis and processing of DNA, RNA, proteins or the major metabolic pathways. As opposed to luxury proteins. (18 Nov 1997) |
| H-protein lipoyltransferase | <enzyme> Requires lipoyl-AMP and apo-h-protein to generate the active h-protein of the glycine cleavage system Registry number: EC 2.3.1.- Synonym: lipoyl-AMP-n(epsilon)-lysine lipoyltransferase (26 Jun 1999) |
| pyp2 protein tyrosine phosphatase | <enzyme> Shares an essential overlapping role with pyp1 ptpase and is 42% identical in sequence in the c-terminal catalytic domain of pyp1; involved in negative regulation of mitosis in fission yeast Registry number: EC 3.1.3.- Synonym: pyp2 ptpase, pyp2 gene product (26 Jun 1999) |
| pyp3 protein tyrosine phosphatase | <enzyme> Acts as mitotic inducer in fission yeast Registry number: EC 3.1.3.- Synonym: pyp3 gene product, pyp3 ptpase (26 Jun 1999) |
| human plasma protein fraction | A sterile solution of selected proteins derived from the blood plasma of adult human donors, containing 4.5 to 5.5 g of protein per 100 ml, of which 83 to 90% is albumin and the remainder is alpha-and beta-globulins; used as a blood volume supporter. (05 Mar 2000) |
| serotonin-binding protein kinase | <enzyme> An aspect of protein kinases EC 2.7.1.37 Registry number: EC 2.7.1.- Synonym: sbp kinase (26 Jun 1999) |
| pyrophosphate-protein phosphotransferase | <enzyme> Not dependent on ATP; inhibited by fluoride Registry number: EC 2.7.1.- (26 Jun 1999) |
| SH protein-tyrosine phosphatase | <enzyme> Has sequence similarity to src-homology region 2 Registry number: EC 3.1.3.- Synonym: sh-ptp3, sh-ptp1, ptp1c, protein-tyrosine-phosphatase 1c, protein tyrosine phosphatase, nonreceptor type 6, ptpn6, shptp1, protein-tyrosine phosphatase shp, shp ptpase, shp-1, shp-2 (26 Jun 1999) |
| silver protein stain | <technique> A silver proteinate complex used in staining nerve fibres, nerve endings, and flagellate protozoa; also used to demonstrate phagocytosis in living animals by the cells of the reticuloendothelial system. (05 Mar 2000) |
| simple protein | Protein that yields only alpha-amino acids or their derivatives by hydrolysis; e.g., albumins, globulins, glutelins, prolamines, albuminoids, histones, protamines. Compare: conjugated protein. (05 Mar 2000) |
| single cell protein | <protein> Protein produced by single cells in culture, especially Candida species, that could be of possible commercial importance in providing food sources from biotechnological processes. (10 Oct 1997) |
| single stranded binding protein | <protein> SSB's are proteins responsiblefor holding the replication fork of DNAopen while polymerases readthe templates. (09 Oct 1997) |
