(6) In chlB mutants, which are known to accumulate the Mo cofactor because of its failure to be inserted as a prosthetic group into proteins such as nitrate reductase, nitrate repression of frd and induction of narC were also intensified by molybdate supplementation.

(8) Expression of narL does not require the fnr gene product, a pleiotropic activator that is required for full expression of narC, frd, and tor.
(9) Mutations in narL prevented the increase in activity in response to nitrate; mutations in chlB, narC, or narI resulted in partial constitutive expression of the chlD-lac fusion: the fusion was regulated by molybdate, but it no longer required the presence of nitrate for maximal activity.
(10) Under anaerobic conditions the narL gene product, in the presence of nitrate, is known to activate transcription of the narC operon, which encodes nitrate reductase.

(16) In chlD mutants believed to be impaired in molybdate transport (or processing), full repression of phi(frd-lac) and full induction of phi(narC-lac) by nitrate did not occur unless the growth medium was directly supplemented with molybdate (1 microM).
(17) arcuatus s. infundibularis - NARC), and posterior (nucl.

(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.

(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.
