| protein kinases | <enzyme> A family of enzymes that catalyze the conversion of ATP and a protein to ADP and a phosphoprotein. Chemical name: ATP-protein phosphotransferase Registry number: EC 2.7.1.37 (12 Dec 1998) |
|---|---|
| protein-losing enteropathies | A series of gastrointestinal disorders which share in common the excessive loss of protein, mainly albumin, across the gut wall. They occur in the stomach (menetrier disease), as well as the small bowel (intestinal lymphangiectases, assorted inflammatory states). They are also occasionally associated with congestive heart failure (again a small bowel protein loss). (12 Dec 1998) |
| protein-losing enteropathy | Condition in which plasma protein is lost to excess into the intestine. This can be due to diverse causes including gluten enteropathy, extensive ulceration of the intestine, intestinal lymphatic blockage, and infiltration of leukaemic cells into the intestinal wall. (12 Dec 1998) |
| protein-lysine 6-oxidase | <enzyme> An enzyme oxidizing peptidyl-lysyl-peptide in the presence of water & molecular oxygen to yield peptidyl-allysyl-peptide plus ammonia & hydrogen peroxide. Chemical name: Protein-L-lysine:oxygen 6-oxidoreductase (deaminating) Registry number: EC 1.4.3.13 (12 Dec 1998) |
| protein malnutrition | Children are particularly prone to develop protein malnutrition. To grow, children have to consume enough nitrogen-containing food (protein) to maintain a positive nitrogen balance whereas adults need only be in nitrogen equilibrium. (12 Dec 1998) |
| protein metabolism | Decomposition and synthesis of protein in the tissues. Synonym: proteometabolism. (05 Mar 2000) |
| protein methylesterase | <enzyme> Hydrolyzes protein methyl esters to yield methanol and unmethylated protein; found in bacterial and human cells Registry number: EC 3.1.1.- (26 Jun 1999) |
| protein methyltransferases | <enzyme> Enzymes that catalyze the methylation of amino acids after their incorporation into a polypeptide chain. S-adenosyl-l-methionine acts as the methylating agent. Registry number: EC 2.1.1 (12 Dec 1998) |
| protein NH2-terminal asparagine deamidase | <enzyme> Converts amino terminal asparagine to aspartic acid; from porcine liver; mw about 33 kD Registry number: EC 3.5.1.- Synonym: porcine pnad (26 Jun 1999) |
| protein-N-pi-phosphohistidine - sugar phosphotransferase | <enzyme> Enzyme II of the system; leve is the the IIb subunit from bacillus subtilis Registry number: EC 2.7.1.69 Synonym: phph-phosphotransferase, phosphohistidinoprotein-hexose phosphotransferase, leve gene product, IIb(lev) (26 Jun 1999) |
| protein N-terminal acetyltransferase | <enzyme> From saccharmyces cerevisiae; encodes a catalytic subunit of an n-terminal acetyltransferase; ard1 and nat1 proteins are subunits of this enzyme Registry number: EC 2.3.1.- Synonym: nat1 gene protein, saccharomyces, yeast protein n-terminal acetyltransferase, n-terminal protein acetyltransferase, ard1 protein (26 Jun 1999) |
| herpes simplex virus protein vmw65 | Trans-acting protein that combines with host factors to induce immediate early gene transcription in herpes simplex virus. (12 Dec 1998) |
| protein o-methyltransferase | <enzyme> An enzyme that catalyses the transfer of methyl groups from s-adenosylmethionine to free carboxyl groups of a protein molecule forming methyl esters. Chemical name: S-Adenosylmethionine:protein O-methyltransferase Registry number: EC 2.1.1.- (12 Dec 1998) |
| herpes simplex virus type 1 UL13 protein kinase | <enzyme> Phosphorylates icp22 and involved in the accumulation of alpha and gamma mrnas and proteins in the infected cells; aa sequence has been determined Registry number: EC 2.7.1.- Synonym: ul13 protein kinase, hsv-1, hsv-1 ul13 protein, hsv-1 ul13 pk, u(l)13 protein kinase, protein kinase ul13 (26 Jun 1999) |
| protein p16 | Product of the p16 tumour suppressor gene, that acts as cyclin-dependent kinase inhibitor of cdk4. (12 Dec 1998) |
