cysteine-1

locus: cys-1

locus_name: cysteine-1

organism_type: B

chromosome_number: VI

chromosome_side: L

link_group: VIL

cultural_requirements: VIL. Between cys-2 (1 to 3%) and ylo-1 (8%) (721,1012). (980) Uses sulfite, thiosulfate, cysteine, or methionine. Original isolate (allele 84605) also had a partial requirement for tyrosine and showed high tyrosinase activity at 25°C but not 35°C (479, 721, 980). These properties reverted, however, whereas the cysteine requirement is stable (479). Used in studies of intra- and interlocus recombination (721, 1015, 1016, 1024-1026).
