lysine-5
locus: lys-5
locus_name: lysine-5
organism_type: B
chromosome_number: VI
chromosome_side: L
link_group: VIL
cultural_requirements: VIL. Right of cyt-2 (6%), aro-6 (3%), and cpl-1 (5 to 7%). Left of un-4 (2%) (1012, PB).Requires lysine. Partial response to glutaric acid (762). Lacks homocitrate synthase activity (464, 762) (Fig. 16). Some alleles such as 37402, called asco, are autonomous ascospore lethals or semilethals, resulting in mostly immature white spores (see reference 1012 for a photograph). Viability of the lys- spores is improved by long incubation (7). With other alleles such as DS6-85, ascospores blacken and germinate normally. Accumulates malate plus citrate on media with limiting lysine concentrations (464). Four complementation groups (12). Allele 37402 called asco.
