CBSE Class 10 Science Lab Manual Experiment 2Aim To study the properties of acids and bases (dilute HCl and dilute NaOH) by their reaction with (a) Litmus solution (Blue/Red) (b) Zinc metal (c) Solid sodium carbonateTheory Hydrochloric acid > Chemical formula of hydrochloric acid is HCl...
Left inset: substituted amino acid residues in the AsCas12a protein around the PAM sequence (TTTN) (E174, S542, K548). Right inset: Active residues in the nuclease domain required for target DNA cleavage. (b, c) Sanger sequencing data of the plasmid containing the target nucleotide ...
Understanding of the enzymatic challenges faced by protein- or nucleic acid-based control agents is essential for development of effective new approaches for stink bug control. The focus of the present study was to compare the biochemical properties of digestive proteases and nucleases in the saliva,...
Substrate oxidation is thought to begin with ion of the substrate α-hydrogen as a proton by an enzyme base. It has been proposed that this role is played by His373, which lies close to the flavin in the crystal structure and interacts with Asp282. It has also been shown before, using...
The conjugate base of acetic acid is acetate, given by CH3COO–. The pH of an ethanoic acid solution of 1.0M concentration is 2.4, which implies that it does not dissociate completely. In its liquid form, acetic acid is a polar, protic solvent, with a dielectric constant of 6.2. ...
Perovskite solar cells (PSCs) are promising photovoltaic technology products because of the rapid growth of their performance and a power conversion efficiency (PCE) of up to 25% . The high efficiency of PSCs mainly comes from the perovskite itself and also from its transport layer ability. The...
peptide 2 as observed in the native hPin1 protein. In the present study, we showed in detail the acid-base properties of all chargedamino acidscontained in the sequence of the short (central) fragment of loop 1 of hPin1 and the influence of acid-base equilibria with the participation of...
The cytochrome P450 (P450) arachidonic acid (AA) monooxygenase metabolizes the fatty acid to a series of epoxy- and hydroxy-acid derivatives. Catalytic turnover requires NADPH, and requires the redox-coupled activation and cleavage of diatomic oxygen, and the delivery of an active form of atomic...
It has been found in the literature that the spider silk properties are highly dependent on its semicrystalline structure which in turn is dependent on the amino acid sequence13. Therefore it is paramount to understand the influence of the sequence on properties. Experimental techniques like X-ray...
High resistance towards traditional antibiotics has urged the development of new, natural therapeutics against methicillin-resistant Staphylococcus aureus (MRSA). Prenylated (iso)flavonoids, present mainly in the Fabaceae, can serve as promising candidat
