Genes

Locus	Cultural Requirements	Link Group	Type
thr-2	IIL. Right of T(NM149) and ro-3 (6 to 25%). Left of T(AR179); hence, left of bal and arg-5 (3 to 18%). Adjoins thr-3 (< 0.1%) (808, 812, PB). Requires threonine. Cannot use other amino acids (1061). Lacks threonine synthetase (352) (Fig. 17). Strongly inhibited by methionine (320, 1061). Known alleles are not heat sensitive, unlike all known thr-3 alleles.

het-c^pa	Two alleles found in lab strains were originally called het-C and het-c. Following the discovery and demonstration of a third allele, het-c^PA, the symbol het-C was changed to het-c^OR and the symbol het-c was changed to het-c^EM. Three specificity types have been recognized and shown to be polymorphic in nature. These are designated het-c^OR, het-c^GR, and het-c^PA.		B
