Fig. 4. Stereo iagra showing the region about
Leu 94 intheL94Smutant protein. Thestructure of
thewild-typeproteinhasbeensuperimposed and is
shown withthick lines, whereasthemutantprotein
structureisdepicted by thin lines. Altered side-chain
conformations for Leu 9 andLeu98areclearly evi-
dent. Hydrogen bonds formedbetweenthehydroxyl
group of Ser94andthe main-chain carbonyl oxygen
atos of Asp 90 andArg91arerepresentedbydashed
lines. Intrahelicalhydrogen bonds formedbetween
thesecarbonyl groups and theamidenitrogen atoms
of Leu 94 and Ile 95 are also epresntedbydashed
lines.
