Enzyme-Substrate Interaction by Nuclear Magnetic Resonance

Open access0 citations

Abstract

The chemical shifts of the nuclear magnetic resonances of N-acetyl-D-tryptophan are measured and compared to those observed when bound to ∝-chymotrypsin. Chemical shift changes of 1 Hz. are reported for a solution with 1% total substrate bound to the enzyme.
