Design Notes
The promoter deletes the C2 and C3 regions of BBa_R0082 (bases 37-74 in BBa_R0082) and inserts an 8-base linker before the -35 and -10 signal region. The efficacy of this promoter versus the full ompC upstream region (BBa_R0082) or the ompF upstream region (BBa_R0084) is currently unknown. The a at base 41 is mutated to t to avoid XbaI site. Speculation that this was a previous assembly site.
