, maeA1Strain Comments:
- galK2(Oc)-- is a GAA(glu) to TAA(ochre) mutation, residue 134. Oller et al.1993. Apparently non-suppressible, since all revertants found were at the ochre site.
- IN(rrnD-rrnE)1-- Inverts the region between rrnD (73.74 min) and rrnE (90.66 min)
- maeR2-- is a regulatory mutation for malic enzyme
- maeA1-- affects NAD-linked malic enzyme (EC220.127.116.11) and is unmapped.
- maeB3-- affects NADP-linked malic enzyme (EC18.104.22.168)
- galK2(Oc) was formerly called gal2
- Oc = ochre(UAA) mutation
- strR = streptomycin resist.
