pta-200,
hisJo-701Strain Comments: - These strains should be stored frozen because of the pta mutation. (G.F-L.Ames)
- hisJo-701-- is a regulatory region for the histidine utilization cluster, hisJ,P,M. Since physical mapping now places the transcr. order his J,M,P, it is presumably in hisJ region.
- Δ(his-gnd)861 was formerly called his-461
- hisJo-701 was formerly called dhuA1
