(1) Our clone also contained a previously unidentified gene, which we propose to designate as narX, as well as a portion of narK.
(2) The phosphorylation of phosphoinositides in the acetylcholine receptor (AChR)-rich membranes from the electroplax of the electric fish Narke japonica has been examined.
(3) A narK deletion mutant, under conditions for the induction of nitrate respiration, was unable to perform nitrate transport.
(4) Loss of transport activity was recovered by transforming the mutant with a narK+ plasmid.
(5) We have isolated a tyrosine-specific protein kinase from the acetylcholine receptor (AChR)-rich membranes of the electric ray Narke japonica.
(6) We could not find the active (Na,K)-ATPase lacking glycoprotein subunit for the enzymes from three different sources (outer medulla of dog kidney, electric organs of Narke japonica and larvae of Artemia salina).
(7) Primer extension analysis identified several transcripts for the narK gene expressed from plasmids.
(8) IHF and Fis proteins are also required for full activation of narK expression, and their roles in DNA bending are discussed.
(9) Unlike the narGHJI operon, the 5' untranslated region of the narK gene contains two putative Fnr-binding-site sequences and two putative NarL-binding-site sequences.
(10) The asymmetric forms of acetylcholinesterase were purified from the electric organs of the electric rays Narke japonica and Torpedo californica, and their properties were compared.
(11) The vast majority [of businesses] are doing the right thing and, frankly, they are as narked as we are about the fact there are some people and businesses who are not doing the right thing.
(12) A Cl- channel in electric organs of Narke japonica was reconfirmed, using a polyclonal antibody, to be a 180k protein composed of two identical 90k units.
(13) Finally, the availability of molybdate and iron ions is necessary for optimal narK expression, whereas the availability of nitrite is not.
(14) The ORFA-narZ intergenic region, however, is about 80 nucleotides long and does not contain the cis-acting elements, NarL and Fnr boxes, nor the terC4 terminator sequence present in the 500 nucleotide narK-narG intergenic region.
(15) A phi (narK-lacZ) operon fusion was induced by nitrate, and its expression was fully dependent on narL+ and fnr+.
(16) Cripps was merely a temporary repository for a public narked off with all politicians: Clegg will have to show that he is more than that if he really is going to rival Churchill.
(17) Although the specific activities of nitrate reductase and nitrite reductase were similar in the two strains, the parental strain accumulated nitrite in the medium in almost stoichiometric amounts before it was further reduced, while the narK mutant did not accumulate nitrite in the medium but apparently reduced it as rapidly as it was formed.
(18) Acetylcholine receptor from Narke japonica electroplax exhibits a fluorescence change upon binding of snake neurotoxins.
(19) The effect of both acetylcholine (ACh) and pancreozymin (CCK-Pz) on the pancreas in vivo as well as in vitro was to reduce both the acinar cell membrane potential and the input resistance narkedly.
(20) Although the role of the narK gene product in cell metabolism remains uncertain, the pattern of narK gene expression is consistent with a proposed role of NarK in nitrate uptake by the cell for nitrate-linked electron transport.
