Genes

Locus	Cultural Requirements	Link Group	Type
lys-1	V. Right of caf-1 (4 to 14%). Left of cyt-9 (5%) and at (1 to 20%) (817; K.S. Hsu, personal communication; PB). (403)Uses lysine, alpha-aminoadipic acid, or epsilon-hydroxynorleucine (alpha-amino-epsilon-hydroxycaproic acid) (399, 400, 684, 1087). Accumulates homocitrate on limiting lysine concentrations (464) (Fig. 16). Fine structure and complementation between alleles (8). Initial allele: 33933.	V	B
thi-4	III. Linked to acr-2, spg, and sc (< 1%). Left of pro-1(3%) and ace-2 (4 to 9%) (812). (482). Requires thiamine (301). Anomalous in condensation of the pyrimidine and thiazole precursors. Very leaky (301). A probable allele called "thi-lo" greatly increases the thiamine requirement of thi-1 strains and decreases the ability to synthesize thiamine from pyrimidine and thiazole. thi-lo strains have no detectable nutritional requirement in the absence of thi-1. thi-lo failed to recombine with thi-4 among 55 scorable progeny (301).

ad-2	IIIR. Between thi-2 (1%) and trp-1 (1 to 7%) (11, 219). (482) Requires adenine or hypoxanthine (682). Controls conversion of phosphoribosylformylglycineamidine to AIR (120) (Fig. 8). Strains carrying allele 70004(t) are heat sensitive (34°C versus 25 C) (682) and osmotic remediable (636). Called complementation group H.	IIIR	B
