In microbial nitrogen metabolism, the occurrence of hydrazine as an intermediate is rare. [36] Hydrazine has been proposed as an enzyme-bound intermediate in the nitrogenase reaction. [37] Recently, using detailed molecular analyses and combining complementary methods, Kartal and coworkers published strong evidence supporting the latter mechanism.
Dissimilatory nitrate reduction to ammonium is a two step process, reducing NO 3 − to NO 2 − then NO 2 − to NH 4 +, though the reaction may begin with NO 2 − directly. [1] Each step is mediated by a different enzyme, the first step of dissimilatory nitrate reduction to ammonium is usually mediated by a periplasmic nitrate reductase.
Citing inadequacies with current practices in listing authors of papers in medical research journals, Drummond Rennie and co-authors, writing in the Journal of the American Medical Association (JAMA) in 1997, called for: a radical conceptual and systematic change, to reflect the realities of multiple authorship and to buttress accountability.
Glutamine synthetase (GS) (EC 6.3.1.2) [3] is an enzyme that plays an essential role in the metabolism of nitrogen by catalyzing the condensation of glutamate and ammonia to form glutamine: Glutamate + ATP + NH 3 → Glutamine + ADP + phosphate Glutamine synthetase catalyzed reaction
Standard manuscript format is a formatting style for manuscripts of short stories, novels, poems and other literary works submitted by authors to publishers.Even with the advent of desktop publishing, making it possible for anyone to prepare text that appears professionally typeset, many publishers still require authors to submit manuscripts within their respective guidelines.
It covers a range of topics for authors and editors in medicine and related health fields. The online edition also has regular updates (style points that have changed since the last edition or new guidance such as how to present new terms like COVID-19 and SARS-CoV-2 or address race and ethnicity in science publication), [ 4 ] a blog (AMA Style ...
Silicon is often used as a substitute for carbon in fictional lifeforms because of its chemical similarities. In cinematic and literary science fiction, when man-made machines cross from non-living to living, this new form is often presented as an example of non-carbon-based life.
The publication was established as an irregular newsletter for members of the BSFA, founded in the same year, but "almost at once it began to produce reviews and essays, polemics and musings, about the nature and state of science fiction." [6] The publication has changed format and periodicity many times over the years. [7]
