nit-2	IL. Right of the T(39311) left breakpoint and of un-5(2%). Left of In(OY323) and leu-3 (12 to 18%) (57, 808, 816, PB). (335, 1135) Cannot use nitrate, nitrite, purines, or most amino acids as a nitrogen source but will grow on ammonia, glutamine, or glutamate. nit-2+ is a major nitrogen control gene and mediates nitrogen catabolite repression. The nit-2 mutant is missing (or has severely reduced levels of) nitrate reductase, nitrite reductase, uricase, xanthine dehydrogenase, allantoinase, allantoicase, L-amino acid oxidase, general amino acid permease, extracellular protease, and an intracellular neutral phenylmethylsulfonyl fluoride-sensitive protease (227, 324, 441, 872, 1001, and references therein). Also affects levels of glutamate dehydrogenases (226) and uptake of uracil and uridine (128). Prevents leaky growth of the mutant am on minimal medium (155). The product of the nit-2gene has been tentatively identified as a nuclear DNA-binding protein, whose affinity for DNA is reduced in the presence of glutamine (433). Allele K31 (called pink) originated in N. sitophila and was introgressed into N. crassa (335); protein product of K31 may show altered mobility (433). Recombination within the nit-2 locus is subject to regulation by rec-1 (157). Heterozygosity for closely linked ss reduces recombination within nit-2 (161). Called amr: ammonium regulation in reference 872.	IL	B
