Abstract excerpt
A new protocol is described for the isotope (15N and 13C,15N) enrichment of hen egg white lysozyme. Hen egg white lysozyme and an all-Ala-mutant of this protein have been expressed in E. coli. They formed inclusion bodies from which mg quantities of the proteins were purified and prepared for NMR spectroscopic investigations. 1H,13C and 15N main chain resonances of disulfide reduced and S-methylated lysozyme were...
