valine

locus: val

locus_name: valine

organism_type: B

chromosome_number: V

chromosome_side: R

link_group: VR

cultural_requirements: VR. Right of at (10%). Linked to ilv-2 (0/135) (PB).Strains carrying alleles 33026 and 33050 appear to be valine auxotrophs, not requiring or responding to added isoleucine (482, PB). Not defective in valyl-tRNA synthetase (J. Evans, personal communication via J.A. Kinsey), as are the only known val mutants of bacteria. Requirement somewhat leaky; not temperature sensitive. Relation to ilv-1 and ilv-2 is uncertain. An ilvmutant strain with an incomplete isolation number, ilv(?6201), was incorrectly designated val(45201) and was the source of linkage data for a locus erroneously shown as val on maps made before 1980.
