cytochrome-4

locus: cyt-4

locus_name: cytochrome-4

organism_type: B

chromosome_number: I

chromosome_side: R

link_group: IR

cultural_requirements: IR. Between the breakpoints of T(AR173); hence, right of the centromere, sn, and arg-3 (2%); left of nuc-1 and lys-4 (808; D.D. Perkins, unpublished data). (87) Deficient in cytochromes aa3 and b. Slow growth. cyt-4-7and strains carrying the three alleles listed below are all defective in splicing of the large mitochondrial rRNA (83; H. Bertrand, personal communication). Phenotype partially suppressed by the electron transport inhibitor antimycin (83). Complements cyt-18 and cyt-19, which are also required for the splicing of large mitochondrial rRNA (83). cyt-3-5, cyt-U-10, and cyt-U-14 of reference 87 are all alleles of cyt-4 and have been designated cyt-4-5, cyt4-10, and cyt-4-14, respectively, by H. Bertrand (personal communication).
