Locus	Cultural Requirements	Link Group	Type
trp-2	VIR. Right of del (0 to 13%). Left of un-23 (5 to 27%), T(OY320), and ws-1 (38%) (818, 822, 1019, PB). Uses kynurenine, anthranilic acid, indole, or tryptophan (96). Kynurenine is utilized by conversion to anthranilate (447). Inferred to be the structural gene for the alpha subunit of the anthranilate synthetase complex (546). The gene product catalyzes anthranilate synthesis with ammonia but not with glutamine as the amino donor (29). Specifies anthranitate synthetase (glutamine linked) in collaboration with trp-1 in trifunctional trp-1+-trp-2+ enzyme aggregate (181, 259) (Fig. 11); see trp-1. Nonsense allele used to isolate supersuppressors (954) and to study enzyme complex restored by supersuppressors (183).	VIR	B
chol-2	VIL. Left of nit-6 (6 to 8%) (812, PB). Requires choline (471). Also uses di- but not monomethylaminoethanol (468) (Fig. 12). Deficient in S-adenosylmethionine:phosphatidyl- monomethylethanolamine methyltransferase (222, 923, 924). Strains carrying the only allele, 47904t, are leaky on minimal medium at 22°C but not at 34°C (501). Phospholipid composition is abnormal on limiting choline (501). Growth is colonial on limiting supplement at 34°C and on minimal medium at 25°C.	VIL	B
