(v. t.) To twist or twine, as hair in making fishing lines.
Example Sentences:
(1) Tests on sensitized guinea pigs (pirl bright white strain) with flowers of chrysanthemum as well as with the two sesquiterpene lactones parthenolide and alantolactone, derived from different Composite species, gave positive patch test reactions.
Purl
Definition:
(v. t.) To decorate with fringe or embroidery.
(n.) An embroidered and puckered border; a hem or fringe, often of gold or silver twist; also, a pleat or fold, as of a band.
(n.) An inversion of stitches in knitting, which gives to the work a ribbed or waved appearance.
(v. i.) To run swiftly round, as a small stream flowing among stones or other obstructions; to eddy; also, to make a murmuring sound, as water does in running over or through obstructions.
(v. & n.) To rise in circles, ripples, or undulations; to curl; to mantle.
(n.) A circle made by the notion of a fluid; an eddy; a ripple.
(n.) A gentle murmur, as that produced by the running of a liquid among obstructions; as, the purl of a brook.
(n.) Malt liquor, medicated or spiced; formerly, ale or beer in which wormwood or other bitter herbs had been infused, and which was regarded as tonic; at present, hot beer mixed with gin, sugar, and spices.
(n.) A tern.
Example Sentences:
(1) The purL gene of Escherichia coli encoding the enzyme formylglycinamidine ribonucleotide (FGAM) synthetase which catalyzes the conversion of formylglycinamide ribonucleotide (FGAR), glutamine, and MgATP to FGAM, glutamate, ADP, and Pi has been cloned and sequenced.
(2) ileS was closely flanked by an unknown open reading frame and by purL and thus is arranged differently from the organizations observed in several eubacteria or in Saccharomyces cerevisiae.
(3) The Killing does Christmas Jumper Day It's a purl Source: Viral Video Chart .
(4) On the basis of the nucleotide sequence of purL, the enzyme was dissected along the polypeptide chain into at least three discrete regions, designated as domains I, II, and III, by genetic complementation tests.
(5) These results support a model that the E. coli purL gene is a fused gene of at least three different gene families.
(6) These measurements indicated 5- to 17-fold coregulation of genes purF, purHD, purC, purMN, purL, and purEK and thus confirm the existence of a pur regulon.
(7) Comparison of the purL control region to other pur loci control regions reveals a common region of dyad symmetry which may be the binding site for the "putative" repressor protein.
(8) The purL gene from Lactobacillus casei, encoding phosphoribosylformylglycinamidine synthase II involved in the de novo synthesis of purines, was cloned and sequenced.
(9) A series of cold-sensitive mutations, affecting the assembly of ribosomes at 20 degrees C, was isolated within the purL to nadB region of the E. coli chromosome and one group, named rbaA, mapped at the same locus as the suppressor mutation, showing close linkage to the RNAase III gene.
(10) The putative purL product of 741 amino acids (M(r) of 79,575) shows 25% and 53% identity to the homologous enzymes from Escherichia coli and Bacillus subtilis, respectively.
(11) Escherichia coli 5'-phosphoribosylformylglycinamide (FGAR) amidotransferase (EC 6.3.5.3) encoded by the purL gene catalyzes the conversion of FGAR to formylglycinamidine in the presence of glutamine and ATP for the de novo purine nucleotide biosynthesis.
(12) Some of the mutants had acquired an additional genetic lesion in the purine de novo biosynthetic pathway, namely a purF, a purL or a purM mutation.
