isoleucine plus valine-1

locus: ilv-1

locus_name: isoleucine plus valine-1

organism_type: B

chromosome_number: V

chromosome_side: R

link_group: VR

cultural_requirements: VR. Between per-1 (4%) and lys-2 (4 to 7%) (3, 14, 489). Left of ilv-2 (<1 to 9% prototrophs; some crosses give anomalous high frequencies [557]). (482)Requires both isoleucine and valine, or corresponding keto acids (557, 10975 1112). Affects dihydroxy acid dehydratase (22, 727) (Fig. 15). Most alleles are leaky (557). Leucine has a sparing effect on valine requirement (99). Called iv-1; groups 2 and 3.
