*In the presence of 0.4-1 mM Tyr, tyrB is repressed and Leu is required for growth in minimal medium. This strategy can only be applicable for a short-term cultivation but not suitable for a long-term cultivation for heterologous expression of foreign genes [Methods 55, 370-378 (2011)].
#In the presence of 0.4-1 mM Tyr, tyrB is repressed and Tyr is required for growth in minimal medium. Under these conditions, this strain can also be used for selective labeling of the input Tyr and/or Ala label(s), although minor diffusion of the input label(s) can occur. Note that this strategy can only be applicable for a short-term cultivation but not suitable for a long-term cultivation for heterologous expression of foreign geness [Methods 55, 370-378 (2011)].

++++RF4, RF5, and RF13 strains have knockouts in both aspC and tyrB genes and therefore require the presence of L-Asp (but not L-Glu) for growth in M63 minimal medium. These strains can be used for selective labeling of selected aromatic amino acid(s) such as Tyr (RF4, RF5, RF13) and/or Trp (RF13). We have NOT tested if these strains could also be used for selective Asp labeling studies (under investigation).

Comments: The genotype of the strain relative to MG1655 is complex, since there are many single nucleotide variations and several 10-20kb differences (Brown & Jun (2015) Genome Announcements, Lyons et. al. (2011) PLoS ONE). There are a particular abundance of differences in the rDNA operons, which in several cases align more closely to E. coli strains DH10B, MDS42, and W.
Particularly relevant genotypes are: λ+ gal+ eut+ pyrE+ ilvG+ rpoS33Am glnV(SupAm) evgA::IS1 Δrfb
