Applications of BBa_I0500

When grown with 0.2% arabinose, promoter is weak-medium. [jb, 5/24/04] Part may not be compatible with MC4100 as cell line is araD 139.
MC4100 is not a good chassis for operating BBa_I0500 (pBad promoter). The feed-forward regulation of the endogenous promoter controlling expression of the arabinose transporter prevents linear induction with increasing arabinose concentration. (Engineered strain from Keasling's lab, used by jrk for operation of the screening plasmid.) [cconboy 04]
Observations of induced expression of GFP (BBa_E0840) are consistent with previous comments about weak promoter signal induction by jb 5/24/04. [melissali, Berkeley iGEM 2005]

PC and AraC are located on the complementary strand, reading right to left as written.

At least one registry stock contains a deletion of the C at base 1194. This is after the transcriptional start but before the translation start, so it may not be significant. Parts with this mutation have been qualitatively observed to function normally.
