Cyanylation of about 2 mol of cysteine residues per mol of enzyme practically abolished the α, γ-elimination activity: the enzyme shows a half-of-the-sites reactivity. L-Norleucine, a competitive inhibitor, which binds to the active site, strongly retarded the reaction of the essential ...

Chemical digestion involves the catalytic processing of food in the gastrointestinal (GI) tract by digestive enzymes, aided by co-secreted substances, required to break down the food substances into simpler molecules for absorption. This process is necessary for transport and subsequent metabolic reaction...
Amphibian species have also been found to usepeptide and proteinpheromones. For example, the structure of the decapeptidesodefrin, the first peptide pheromone identified in a vertebrate, was isolated from male red-bellied newts in 1995 using RP-HPLC purification. Similarly, a number of pheromones ...
Norleucine is isosteric with methionine and is expected to have little effect on the protein structure and function [11]. We also added a polyhistidine tag (His6) at the N terminus of the synthetic polymerase to facilitate further protein purification after folding of the enzyme (see Materials...
