suppressors of trp-3 allele td2

locus: su(trp-3td2)-2

locus_name: suppressors of trp-3 allele td2

organism_type: B

chromosome_number: III

chromosome_side:

link_group: III

cultural_requirements: III. Linked to leu-1 (22%) (581). Allele specific. Suppresses allele td2 but does not suppress td6, td7l, or any other allele from td1 through td34 (580, 1169). This and the other listed suppressors of td2 were not tested on later trp-3 alleles that fall in the same complementation group as td2. Although suppressed mutants grow on minimal medium, growth is stimulated by addition of tryptophan. Suppressed trp-3;sucolonies are morphologically distinguishable from those of the wild type. Tryptophan synthetase is formed at levels below that of the wild type. Originated in trp-3 allele td2 (originally numbered S1952) (1166, 1169). Called su-2 (388) and su2 (1169).
