2 To whom correspondence should be addressed
The gene coding for 3-isopropylmalate dehydrogenase of Thermus thermophilus was cloned and expressed in Escherichia coli. The extracted enzyme was crystallized in a suitable size for X-ray crystallographic studies. The crystals have a space group of P3121 or P3221 with a = b = 78.6 Å and c = 157.4 Å.
