pyrimidine-6

locus: pyr-6

locus_name: pyrimidine-6

organism_type: B

chromosome_number: V

chromosome_side: R

link_group: VR

cultural_requirements: VR. Between asn (6%) and un-9 (2%) (156, 818). (133, 134) Requires uracil or other pyrimidine. Lacks dihydroorotase activity (133, 134) (Fig. 20). On a small amount of uridine, a strain(s) carrying the only allele (DFC37) grows, after a pause, well beyond the level normally supported by the supplement; at no time is dihydroorotase detectable (134).
