methionine-9

locus: met-9

locus_name: methionine-9

organism_type: B

chromosome_number: VII

chromosome_side: R

link_group: VIIR

cultural_requirements: VIIR. Between met-7 (10[-4]) and wc-1 (1 to 2%) (725). (815) Requires methionine; cannot use precursors (290, 718, 725). Apparently contiguous with met-7, q.v. (725). Functionally distinct from met-7. The mutant met-9 retains the met-7+ function, producing cystathionine-gamma-synthase (547). Allele NM43 is heat sensitive (725).
