- A certain plant storage protein, after being isolated, was digested using both 8N H2SO4 and conc. Ba(OH)2. The resulting hydrolysates were then analyzed for amino acid composition using paper chromatography with EtOH-NH3-H2O (80:10:10) as the solvent system and ninhydrin as the visualizing agent. Name the amino acids found in the acid hydrolysate labelled 1-5.Pyridoxal phosphate (PLP) is a coenzyme for the enzyme ornithine aminotransferase. The enzyme was purified from cells grow in PLP = deficient media as well as from cells grown in media that contained pyridoxal phosphate. The stability of the two different enzyme preparations was then measured by incubating the enzyme at 37°C for different lengths of time and then assaying for the amount of enzyme activity remaining. The following results were obtained. (a) Why does the amount of active enzyme decrease with the time of incubation? (b) Why does the amount of enzyme from the PLP deficient cells decline more rapidly?The SARS-Cov-2 virus is the virus that cause COVID-19. The viral protease is a known target for finding potential viral inhibitor.
