Gene: nitrate nonutilizer-1 IR
nitrate nonutilizer-1
locus: nit-1
locus_name: nitrate nonutilizer-1
organism_type: B
chromosome_number: I
chromosome_side: R
link_group: IR
cultural_requirements: IR. Right of Tp(T54M94) and ad-9 (3 to 15%). Left of cyh-1(6%) (466, 496, 816). (482)Cannot use nitrate or hypoxanthine as a nitrogen source, but uses nitrite, ammonia, or amino acids (1000). Does not prevent formation or nitrate reductase apoprotein (999), but lacks the molybdenum-containing cofactor common to nitrate reductase and xanthine dehydrogenase (591, 741) (Fig. 19 and 24). The nitrate reductase in nit-1 extracts does not catalyze the complete electron transport sequence from NADPH to N03 but does catalyze the initial part of this sequence if a suitable electron acceptor (e.g., cytochrome c) is provided (999). See reference 198 for a model of interaction of nit-1 and nit-3 gene products. See references 226, 999, and 1000 for regulation.
