Fluorine-19 nuclear magnetic resonance spectroscopic study of fluorophenylalanine- and fluorotryptophan-labeled avian egg white lysozymes.

Biochemistry 33(17) , 5238-45, (1994)

We report the 470-MHz (11.7 T) 19F solution nuclear magnetic resonance (NMR) spectra of 2-, 3-, and 4-fluorophenylalanine incorporated into the egg white lysozymes (EC 3.2.1.17) of chicken, pheasant, ...

Atomic mutations at the single tryptophan residue of human recombinant annexin V: effects on structure, stability, and activity.

Biochemistry 38(33) , 10649-59, (1999)

The single tryptophan residue (Trp187) of human recombinant annexin V, containing 320 residues and 5328 atoms, was replaced with three different isosteric analogues where hydrogen atoms at positions 4...

Incorporation of tryptophan analogues into staphylococcal nuclease, its V66W mutant, and Delta 137-149 fragment: spectroscopic studies.

Biochemistry 37(25) , 8938-46, (1998)

We have biosynthetically incorporated several tryptophan analogues into three forms of Staphylococcal nuclease to investigate the spectroscopic characteristics of these "intrinsic" probes and their ef...
