Web14. feb 2024 · Chemical libraries for the modified residues 4-19 F-Phe (PFF) and 4-19 F-Trp (4FW) were obtained from the Protein Data Bank. Visual structure comparisons and calculations of root-mean-square ... WebFour Phe residues consisting of catalytic pocket and surrounding the docked substrate, were substituted with Ala, resulting in decrease in k(cat)/K(m) to various extents. Substitution of two residues (Val267 and Cys267) localized at the deep end of the catalytic pocket also yielded negative influence on the substrate hydrolysis. el toro heating and air
