homoserine

locus: hom

locus_name: homoserine

organism_type: B

chromosome_number: I

chromosome_side: R

link_group: IR

cultural_requirements: IR. Right of arg-6 (1%), Tp(T54M94), and al-2 (2 to 7%). Between the breakpoints of T(STL76) and T(4637); hence, left of al-1 (cnr (1%), probably to the left (789, 812). (1061, 1063)Uses homoserine, or methionine plus threonine (1063). Affects aspartate beta-semialdehyde dehydrogenase (518) (see Fig. 17). Inhibited on complex complete medium and by methionine and other amino acids (1063); supplemented minimal medium should therefore be used. Symbol changed from hs.
