Meprobamate is the most important representative of the chemical class of propanediol carbamates (Fig. 1). It was introduced into therapy in 1955 as the first agent specifically intended for the treatment of anxiety and related emotional disturbances and found immediate broad acceptance. After the ...
This duality of EC numbers makes it possible to relate biological information (such as enzymatic genes) to chemical reactions in metabolic pathways [4]. EC number is a four-level hierarchy; for instance, 3.1.1.1. The first digit indicates the kind of chemical reactions that an enzyme can ...
Structure of CedA bound to the open-promoter complex To gain further insight into the mechanism of CedA, we used cryo-EM to solve the structure of CedA bound to the RNAPσ70-open-promoter complex. Purified RNAPσ70 holoenzyme was first incubated with 85-bp DNA representing −60 to +25...
Write the Lewis structure of glycine when this amino acid is dissolved in water. (Hint: Consider the relative base strengths of the –NH2 and −CO2−−CO2− groups.) Boric acid, H3BO3, is not a Brønsted-Lowry acid but a Lewis acid. Write an equation for its reaction with wat...
