leu-3	IL. Right of the In(OY323) left breakpoint and nit-2 (12 to 18%). Left of cyt-1 (5 to 8%) and T(OY321) (57, 816, PB; D.D. Perkins, N.B. Raju, and E.G. Barry, in preparation). (868)Requires leucine (867, 868). Regulatory mutation; prevents synthesis of alpha-isopropylmalate isomerase and beta-isopropylmalate dehydrogenase and prevents full derepression of alpha-isopropylmalate synthetase; also involved in regulation of isoleucine and valine synthesis, q.v. (427, 771, 833) (Fig. 15). The original allele, 47313, is leaky, but some other alleles, e.g., R156, are not.	IL
