Nitric oxide synthases: structure, function and inhibition

WK Alderton, CE Cooper, RG Knowles - Biochemical journal, 2001 - portlandpress.com
This review concentrates on advances in nitric oxide synthase (NOS) structure, function and
inhibition made in the last seven years, during which time substantial advances have been …

Denitrification

R Knowles - Microbiological reviews, 1982 - Am Soc Microbiol
… Topp and R. Knowles,unpublished data), they may be responsible also for the persistence
of the N20 maximum between the dissimilatory sink in the hypolimnion and diffusion lossto …

[HTML][HTML] Nitric oxide synthases in mammals.

RG Knowles, S Moncada - Biochemical Journal, 1994 - ncbi.nlm.nih.gov
Nitric oxide is an inorganic free radical gas, of formula* N= O (abbreviated as NO). The discovery
in 1987/88 that vascular endothelial cells are able to synthesize NO from L-arginine as …

Formation of nitric oxide from L-arginine in the central nervous system: a transduction mechanism for stimulation of the soluble guanylate cyclase.

RG Knowles, M Palacios… - Proceedings of the …, 1989 - National Acad Sciences
A soluble enzyme obtained from rat forebrain catalyzes the NADPH-dependent formation of
nitric oxide (NO) and citrulline from L-arginine. The NO formed stimulates the soluble …

Acetylene inhibition of nitrous oxide reduction and measurement of denitrification and nitrogen fixation in soil

T Yoshinari, R Hynes, R Knowles - Soil Biology and Biochemistry, 1977 - Elsevier
Reduction of N 2 O in moist soil was inhibited completely by 10 −2 atm C 2 H 2 and partially
by 10 −5 atm C 2 H 2 . The effect of C 2 H 4 was 10 4 times less than that of C 2 H 2 . …

Induction of calcium-dependent nitric oxide synthases by sex hormones.

…, I Lizasoain, SA Baylis, RG Knowles… - Proceedings of the …, 1994 - National Acad Sciences
We have examined the effects of pregnancy and sex hormones on calcium-dependent and
calcium-independent nitric oxide synthases (NOSs) in the guinea pig. Pregnancy (near term) …

Six challenges for neural machine translation

P Koehn, R Knowles - arXiv preprint arXiv:1706.03872, 2017 - arxiv.org
We explore six challenges for neural machine translation: domain mismatch, amount of
training data, rare words, long sentences, word alignment, and beam search. We show both …

[HTML][HTML] 1400W is a slow, tight binding, and highly selective inhibitor of inducible nitric-oxide synthase in vitro and in vivo

…, RJ Kiff, F Laszlo, BJR Whittle, RG Knowles - Journal of Biological …, 1997 - ASBMB
N-(3-(Aminomethyl)benzyl)acetamidine (1400W) was a slow, tight binding inhibitor of human
inducible nitric- oxide synthase (iNOS). The slow onset of inhibition by 1400W showed …

C Bédard, R Knowles - Microbiological reviews, 1989 - Am Soc Microbiol
… SR Megraw and R. Knowles (unpublished data) have obtained strong evidence that, under
certain conditions, essentially all of the NH4' oxidation measured in a particular humisol is …

The influence of water table levels on methane and carbon dioxide emissions from peatland soils

TR Moore, R Knowles - Canadian Journal of Soil Science, 1989 - cdnsciencepub.com
The evolution of carbon dioxide and methane was measured from laboratory columns packed
with surface (0–30 cm) materials representing a fen, a bog and a swamp and with varying …
