Robert Eggers’ 2019 film The Lighthouse provides an idiosyncratic representation of the mermaid as a Jungian anima in that revolves around homoerotic tension between two lighthouse keepers on remote, windswept island. While theme is essentially minor aspect film, juxtaposed with other mythological motifs, it significant for intensity passions catalyses one film’s male leads. Analysing its scrip...

Acetohydroxyacid synthase (Ec 2.2.1.6) catalyses the thiamine diphosphate-dependent reaction between two molecules of pyruvate yielding 2-acetolactacte and CO2. The enzyme will also utilise hydroxypyruvate with a k(cat) value that is 12% of that observed with pyruvate. When hydroxypyruvate is the substrate, the enzyme undergoes progressive inactivation with kinetics that are characteristic of s...

Glutamine synthetase (EC 6.3.1.2) catalyses the formation of glutamine from glutamate and ammonia coupled with the breakdown of ATP to ADP and phosphate. In the presence of ATP, glutamate and Mg, but in the absence of ammonia the enzyme forms a complex containing glutamate, ADP and phosphate; with ammonia, this complex forms glutamine, ADP, phosphate and free enzyme. The presence of ATP is nece...

It is shown here that rat liver pyruvate dehydrogenase (PDH) kinase activator protein (KAP) catalyses ATP-dependent inactivation and [32P]phosphorylation of pig heart PDHE1 and of yeast (Saccharomyces cerevisiae) PDH complex devoid of PDH kinase activity, that fluorosulphonylbenzoyladenosine inactivates rat liver KAP and the intrinsic PDH kinase of rat liver PDH complex, and that KAP, like PDH ...

A simple one-step synthesis was accomplished for the preparation of N-phosphoramidophosphonates by a direct reaction of phosphoramidate (1) with heterocyclic aldehydes (2a-j) and dialkyl phosphites at 60-70 degrees C in the presence of tetramethylguanidine. The tetramethylguanidine not only catalyses this reaction but also helps to form pure products in high yields in lesser time. They exhibite...

The Solanaceae plants produce a variety of interesting biologically active products including the steroid alkaloids solanidine, nicotine and tropane alkaloids. Putrescine N-methyltransferase (PMT) is an enzyme that catalyses s-adenosylmethionine-dependent methylation of putrescine in one of the primary steps of nicotine and tropane alkaloids biosynthesis pathway. Two tobacco members of the AP2/...

Carbon nanotubes are of great interest due to their high surface area and rich edge sites, which are favorable for wide applications. Here, a simple and efficient routine is presented by decoration of multi-wall carbon nanotube (MWCNT) with nickel oxide (NiO) nanoparticles.The morphologies of NiO-MWCNT  were  investigated  by  using scanning  electron  microscope  (SEM)  and energydispersive X-...

A systematic study of the effect of substitution within the beta-amino acid framework indicates that both beta(2)- and beta(3)-amino acids catalyse the Hajos-Parrish-Eder-Sauer-Wiechert reaction with poor to reasonable levels of enantioselectivity. These results led to the evaluation of the conformationally constrained beta-amino acid (1R,2S)-cispentacin, which catalyses the Hajos-Parrish-Eder-...
