pro- |
<prefix> Prefix (from both Greek and Latin) with many meanings including before, in front of, preceding, on behalf of, in place of, and the same as. Used as a word, pro of course means professional and, in medicine, it is short for prothrombin. (12 Dec 1998) |
pro-lactase-phlorizin hydrolase |
<chemical> Synonym: pro-lph (26 Jun 1999) |
pro-ocytocin-neurophysin convertase |
<enzyme> Cleaves pro-ocytocin-neurophysin at the cooh-terminal side of arg 12 to release the bioactive peptide Registry number: EC 3.4.99.- Synonym: pro-ot-np convertase, pro-oxytocin-neurophysin convertase (26 Jun 1999) |
pro-opiomelanocortin |
<chemical> A precursor protein, mw 30,000, synthesised mainly in the anterior pituitary gland but also found in the hypothalamus, brain, and several peripheral tissues. It incorporates the amino acid sequences of acth and beta-lipotropin. These two hormones, in turn, contain the biologically active peptides msh, corticotropin-like intermediate lobe peptide, alpha-lipotropin, endorphins, and methionine enkephalin. Chemical name: Opiomelanocortin, pro- (12 Dec 1998) |
pro-oxidants |

pro-transforming growth factor-alpha processing protease |
<enzyme> Converts membrane-bound protgf-alpha to soluble tgf-alpha; mw 84 kD Registry number: EC 3.4.21.- Synonym: protgf-alpha converting enzyme, protgfalpha processing protease (26 Jun 1999) |
proaccelerin |
<chemical> Heat- and storage-labile plasma glycoprotein which accelerates the conversion of prothrombin to thrombin in blood coagulation. Factor v accomplishes this by forming a complex with factor xa, phospholipid, and calcium (prothrombinase complex). Deficiency of factor v leads to owren's disease. Chemical name: Blood-coagulation factor V (12 Dec 1998) |

proacrosomal granule |
<cell biology> Small carbohydrate-rich granule's appearing in vesicles of the Golgi apparatus of spermatids. They coalesce into a single acrosomal granule contained within an acrosomal vesicle. (05 Mar 2000) |
proactinium |
<chemical> Protactinium. A radioactive element of the actinide group of metals. It has the atomic symbol pa, atomic number 91, and atomic weight 231. It decays by alpha-emission. Chemical name: Protactinium (12 Dec 1998) |
proactivator |
<biochemistry> A substance that, when chemically split, yields a fragment (activator) capable of rendering another substance enzymatically active. (05 Mar 2000) |
