Computational method for relative binding energies of enzyme-substrate complexes.
A computational method for estimating the relative binding free energies of enzyme-substrate complexes is described that combines electrostatic and solvation models and X-ray crystallographic data. The polar contribution is evaluated by the Poisson-Boltzman equation. The nonpolar contribution is evaluated by solvent transfer data and surface area calculations. This algorithm was used to calcula...
متن کاملDirect characterization of enzyme-substrate complexes by using electrosonic spray ionization mass spectrometry.
Numerous reports have cited the use of electrospray ionization (ESI) mass spectrometry to characterize intact, multiplycharged proteins and protein complexes. Herein we describe the application of a variant method, electrosonic spray ionization (ESSI), to monitor dynamic changes associated with formation of binary and ternary complexes, such as enzyme–substrate and enzyme–substrate–inhibitor sy...

The substrate binding site of pepsin.
In earlier reports from this laboratory, a series of new synthetic substrates for pepsin was described.'-' These compounds are of the general type Z-His-X-YOAI\e4 where X and Y are the residues of amino acids such as L-phenylalanine, p-nitro-L-phenylalanine, L-tyrosine, L-tryptophan, and L-leucine; the enzymic action is limited to the cleavage of the X-Y bond. One of the substrate analogues pre...
