Affinity chromatography does not require the molecular weight, charge, hydrophobicity, or other physical properties of the analyte of interest to be known, although knowledge of its binding properties is useful in the design of a separation protocol. [5]
Stereoisomers of Soman, a G-series nerve agent and suicide inhibitor of acetylcholinesterase.Note the non-carbon chiral center.. In biochemistry, suicide inhibition, also known as suicide inactivation or mechanism-based inhibition, is an irreversible form of enzyme inhibition that occurs when an enzyme binds a substrate analog and forms an irreversible complex with it through a covalent bond ...
Even though this class of enzyme has been extensively studied, its mechanism of action is still being debated. Two mechanisms have been proposed: a radical mechanism and a nucleophilic mechanism. The radical mechanism is less generally accepted because no spectral or electron paramagnetic resonance evidence exists for the presence of a radical ...
This article needs attention from an expert in biochemistry.The specific problem is: someone with a solid grasp of the full scope of this subject and of its secondary and advanced teaching literatures needs to address A, the clear structural issues of the article (e.g., general absence of catabolic biosynthetic pathways, insertion of macromolecule anabolic paths before all building blocks ...
BCCP (Biotin Carboxyl Carrier Protein), a protein domain biotinylated by BirA enabling recognition by streptavidin; BromoTag, a "bump-and-hole" mutated version of the second bromodomain of Brd4, Brd4-BD2 L387A, that can be highly selectively bound by tag-specific PROTAC degrader AGB1 to form a ternary complex between the "BromoTagged" protein and the E3 ligase VHL, leading to ubiquitination of ...
“A lot of people always ask me how I do gymnastics with such long nails. To tell you the truth, they actually help me with my technique,” Chiles, 23, recently told the Associated Press ...
iCLIP [1] [2] [3] (individual-nucleotide resolution crossLinking and immunoprecipitation) is a variant of the original CLIP method used for identifying protein-RNA interactions, [4] which uses UV light to covalently bind proteins and RNA molecules to identify RNA binding sites of proteins.
Inosine 5′-monophosphate dehydrogenase (IMPDH) is a purine biosynthetic enzyme that catalyzes the nicotinamide adenine dinucleotide (NAD +)-dependent oxidation of inosine monophosphate (IMP) to xanthosine monophosphate (XMP), the first committed and rate-limiting step towards the de novo biosynthesis of guanine nucleotides from IMP.
