Example Sentences:
(1) Addition in the cultures of 4-deoxypyridoxine, a potent antagonist of vitamin B6 coenzymes, concurrently with the mitogen, inhibits the induction of serine hydroxymethyltransferase.
(2) Amino acid analysis indicated a significant number of serine amino acids: N-terminal sequence data demonstrated a high level of homology; and trypsin digestion followed by reversed-phase HPLC indicated the possibility of multiple phosphorylation sites.
(3) Plasminogen activator inhibitor-1 (PAI-1), the primary physiological inhibitor of tissue-type plasminogen activator (t-PA) in plasma, is a serine proteinase inhibitor (serpin) that forms a 1:1 stoichiometric complex with its target proteinase leading to the formation of a stable inactive complex.
(4) The alterations in DS frontal cortex included decreases in (n-6) and increases in (n-3) groups in choline and ethanolamine phosphoglycerides (CPG and EPG), as had previously been found in EPG and serine phosphoglyceride (SPG) of the DS fetal brain.
(5) A significant proportion of the soluble protein of the organic matrix of mollusk shells is composed of a repeating sequence of aspartic acid separated by either glycine or serine.
(6) Serine (12.0-18.2%), tyrosine (5.8-9.0%) and glycine (4.5-7.1%), along with arginine, make up the bulk of the amino acid residues in these molecules.
(7) Serine inhibited the ethanolamine incorporation by this preparation and ethanolamine inhibited the serine incorporation.
(8) The exceptions were the levels of threonine, glutamine, serine and histidine, which were three times greater in brain than in serum.
(9) Phosphorylation of serine occurs mostly (Sp H1) or entirely (Sp H2B) on the N-terminal portions of these molecules.
(10) The structural region contains serines, threonines, and cysteines at exactly the positions required to give mature nisin by a series of post-translational modifications involving dehydration of serines and threonines to dehydro forms, and cross-linking with cysteine residues.
(11) Two-dimensional phosphopeptide map analysis revealed that the major sites of tyrosine and serine phosphorylation in PLC-gamma 1 from activated Jurkat cells are the same as those in PLC-gamma 1 from cells treated with peptide growth factors such as epidermal growth factor and platelet-derived growth factor.
(12) Phosphate appears to be incorporated solely into serine residues.
(13) Other amino acids (glutamine, taurine, asparagine, alanine, serine) were only altered in single brain regions, or were not altered at all (aspartate, glycine, threonine, arginine).
(14) To gain further insight into the side chain requirement at position 177 that confers maltose recognition, further substitutions of isoleucine, leucine, phenylalanine, proline, and serine have been made via site-directed mutagenesis.
(15) Phosphoamino acid analysis showed that histidyl-tRNA synthetase is phosphorylated on serine, as has previously been shown for threonyl-tRNA synthetase of CHO cells.
(16) We present evidence that over-expression of human plasminogen, the precursor to the serine protease plasmin, can be cytotoxic to mammalian cells.
(17) Sodium Acetate, Arginine, Cysteine, Leucine, Norleucine, Methionine and Serine (more than 50%).
(18) Pancreatic and urinary kallikreins failed to form the typical serine proteinase complex with alpha2M (alpha2-macroglobulin).
(19) Serine deletion was also shown to be position-specific.
(20) The data obtained testify to the presence in the granular fraction of the endopeptidase LTH-converting activity which is sensitive to pepstatin A, an aspartyl proteinase inhibitor as well as to chelators and a serine proteinase inhibitor.
Siskin
Definition:
(n.) A small green and yellow European finch (Spinus spinus, or Carduelis spinus); -- called also aberdevine.
(n.) The American pinefinch (S. pinus); -- called also pine siskin. See Pinefinch.
Example Sentences:
(1) There was no effect of B on basal metabolic rate of either species, but nocturnal metabolic rate varied significantly less over the 3-h period of measurement in B-treated sparrows and siskins than in control birds.
(2) Resting metabolic rates of Gambel's white-crowned sparrows (Zonotrichia leucophrys gambelii) and pine siskins (Carduelis pinus) were evaluated at thermoneutral temperatures before and after administration of corticosterone (B) at physiological doses.
